How much can you tow with a half-ton pickup? It might surprise you that there is no single answer to this. It may also surprise you that your very light travel trailer may be much more than your V8 pickup is supposed to handle.
What a half-ton pickup can tow varies widely depending on how it’s configured. Just because your truck has the big V8 and a tow receiver and, potentially, even a “tow package” doesn’t mean you can tow a trailer even if that trailer has the word “light” or “half-ton towable” as part of its description.
Even within the same manufacturer, the capability of any half-ton truck model can vary substantially – even with the same engine choice. And there is also the matter of how close to the edge of any vehicle’s capabilities an owner should even get – which is subjective but still a safety concern.
And, really, it’s not even how much you can tow that’s the most important consideration. It’s how easily you can stop or control the trailer if there is sway that is the most important factor, especially if things get squirrelly out there on the road.
Nonsense, you say? Fine. Let’s look at the numbers.
Use my Ram 1500 for an example
Because I own one of these, I’ve chosen to look at the Ram 1500 for this example.
You might take a look at this thing and see the big 5.7 liter V8 with almost 400 horsepower and 410 ft-lbs of torque and think that you could tow your house. Perhaps add your neighbor’s house too.
But in configuring that truck, you have choices including gear ratios in the axle which can be favored to either maximize efficiency or maximize towing. For example, the 2021 Ram 1500 with a 6’4” box offers either a 3.21 or 3.92 rear axle ratio. Essentially, the more the engine spins, the more it is able to tow. (I realize this is a huge oversimplification, but bear with me.)
So, the 3.21 axle ratio is designed more for fuel mileage, whereas the 3.92 is designed more to deliver power to the ground. Yet, looking at all the Ram pickups in the lot, you couldn’t tell the difference from one to the next with just this one factor in play. And it’s just one factor in many.
No single definition of a half-ton truck
There isn’t a singular definition of a half-ton truck. There are also all sorts of interesting engine choices nowadays. For example, Ford has its EcoBoost series which is a twin-turbocharged six-cylinder engine that is the equal of most V8 engines. Even more, Chevrolet has a turbocharged four-cylinder engine that is rated to tow within 20 lbs. of that company’s V8 in the same truck.
Furthermore, if you choose America’s best-selling truck, the Ford F150, the standard engine in most of those is also an EcoBoost but with a small 2.7-liter turbocharged V6. Those trucks come with a receiver hitch and can even be outfitted with towing features from the factory. Ford even claims those trucks can tow up to 9,000 lbs. with a 2,470 lb. payload capacity.
But in a Facebook group I moderate, this configuration is probably the truck where people ask about recommendations for replacing the truck with something more powerful. The numbers say one thing – the real world along with its pesky gravity and physics demonstrate something different.
So, you could see two nearly identical half-ton trucks with wildly different towing and cargo capacities. To make it even more confusing, just one option can make a huge difference in how capable a truck is for towing.
Full-sized pickups have many variations
Full-sized pickups are an incredible mixture of features and options and engines, unlike anything you’d find in passenger cars or even SUVs. In addition to the variables described above for gear ratio, things like two-wheel drive or four-wheel drive, cab configuration and more will absolutely affect the overall tow rating of any pickup – but particularly half-ton trucks.
Tires, brake sizes, spring rates and a myriad of factors affect what a truck is rated to tow, and reality also dictates how much it can safely tow.
Furthermore, as truck fuel economy standards imposed by the federal government increase, you’re going to see more and more unusual engine choices come to market – exemplified by GM’s turbocharged four-cylinder pickup engine in full-sized trucks. Ford’s hybrid F-150 has been getting tremendous press – not because of the 4 mpg fuel economy boost, but because of the power port in the bed that taps into the lithium battery pack.
What can your truck carry?
So, how do you know what your truck can carry? It’s actually rather simple after all this. Inside the door of every truck sold in the U.S. is a sticker that will display the Gross Combined Weight Rating (GCWR) of the truck and trailer as defined by the Society of Automotive Engineers (SAE) J2807 towing standards.
From that information, you subtract the weight of the truck and anything in it. That gives you the maximum weight of the trailer it can accommodate. But wait… there is also a maximum cargo-carrying capacity of any truck, also listed on the door jamb.
If you have a trailer, you need to know the tongue weight or pin weight in the case of a fifth wheel as you go camping. So, not the weight from the manufacturer, but what it honestly weighs in the real world with all your travel stuff loaded in it. For the sake of guessing, you can go with the Gross Vehicle Weight Rating (GVWR) of the trailer as a safe assumption. But you’re best off having the whole thing weighed at a CAT scale or comparable scale.
Numbers on my truck
So, with all this in mind, let’s look at my own truck. Plug in your numbers accordingly.
We’re looking at a truck that can tow, according to the manufacturer, 8,520 lbs. with a cargo carrying capacity of 1,900 lbs. Wow, that’s almost a ton of cargo. Let’s load up! But wait…
So, within that, you have to add the tongue weight of the trailer. If we look at an average “light” trailer like the Rockwood Mini Lite 2514s that I reviewed a few years ago, you’ll see it weighs an estimated 5,879 lbs. with a hitch weight of 585 lbs. So that means you’re in the clear, right? Well, hold on.
People underestimate weight of contents in trailer
People often underestimate how much their contents weigh in a trailer, so let’s go with the Gross Vehicle Weight Rating of that trailer as mentioned above. Now we’ve got a rig that could weigh 7,588 lbs. That means the hitch weight could be about 1,138 lbs.
Typically, about 15 percent of a travel trailer’s total weight is actually carried by the tow vehicle in the form of tongue weight. Those cast iron pots, bicycles, all that water in the trailer, the food in the fridge and those winter jackets all count. More often than not, people load RVs to the hilt without thinking about it. You can’t ignore the storage tanks, tools, those wood blocks and all sorts of other stuff though, can you?
But weight, there’s more. (See what I did there?) You, your spouse, the kids, that firewood, the generator and those ice chests are all cargo in the tow vehicle. So let’s say you and your spouse add up to 400 lbs. (we won’t be specific who weighs what here), which is not unreasonable. A couple of kids at 50 lbs. each, plus Fido, who weighs as much as the kiddos. That means there are 550 lbs. of people and pets alone.
Now you’ve also got 25 gallons of gasoline at 6.3 pounds per gallon, so add 157 pounds to the tow vehicle. Yep, it’s cargo, too.
Don’t forget the firewood, generators, bicycles, leveling wood blocks, picnic table, etc.
Also important is the hitch you have on the back of the truck. I weighed my own Equal-i-zer hitch and was surprised it was almost 100 lbs. That’s weight taken off the total weight my truck is designed to carry.
Don’t just look at the brochure info
So, while you might look at the brochure for the truck and the trailer and think all is well in the world, in reality, you may be way over capacity. And that’s with a trailer that has the word “Lite” in the name! I’ve seen people with three kids and two dogs and a camper shell full of stuff want to tow something like the Cherokee 294BH Bunkhouse Travel Trailer we reviewed. In fact, I had a customer show up with an SUV wanting to tow one of these. It didn’t pencil out even before he added his four kids and any content at all in the trailer.
In theory, if you just look at the brochure, you’re fine. Until you do the real numbers. And then you may be endangering those three kids, two dogs and your spouse with a vehicle that is severely underrated to tow what you want to tow.
And should you even tow an RV?
Interestingly, Ram’s towing page shows any of their half-ton trucks for towing “boats, ATVs and trailers” but indicates the Ram 2500 for towing “horses, RVs and just about anything else.” So aren’t RVs basically trailers?
Well, yes. Sort of.
RVs are a gigantic wind block which brings another factor into the towing realm. In addition to the actual weight of the vehicle, there’s also overcoming the aerodynamic drag of the vehicle. The rear springs in Ram’s 2500 model are a totally different design than in the 1500, and payloads are significantly higher at 3,330 lbs. compared to 1,900 lbs. for the Ram 1500 Big Horn – which is the model I have.
Aerodynamic drag of trailer
One of the things I really dislike about SAE’s J2807 is that it’s measured with flat trailers with heavy loads on them. This is all well and good, but it doesn’t reflect the incredible aerodynamic drag that is a travel trailer or fifth wheel. This is why I recommend never exceeding about 70% of your truck’s towing capacity because there really isn’t a way for us mere mortals to factor in these numbers.
It is relatively easy to calculate what your tow vehicle can tow with the numbers provided by the manufacturers. But it was surprising to many customers when I was working at the RV dealership that we would tell them a specific half-ton pickup wasn’t suitable to tow a trailer they were interested in. Yes, even those “light” trailers.
There were times we would lose a sale to a customer when we were honest with them, but we always thought this was preferable to their losing their lives due to a tow vehicle poorly suited to what they wanted to tow.

Good article, Tony. Many overlook this and focus only on the tow rating.
Interestingly, I see landscapers pulling extremely well loaded box trailers full of riding lawn mowers and tools with 1500’s. Contractors with utility bodies propped with helper springs pulling tool trailers that would add digits to the weigh ticket. I can understand why the average RV’er might be led to believe their truck can pull the trailer they’ve picked out on the lot.
They may be getting away with it because they don’t do long trips at high speed, and when the truck breaks down they don’t realize it was because the trailer weighed too much.
I appreciate an article such as Tony’s. I recommend more articles and those articles start with CCC of the tow vehicle, ALL IN CAPS. I routinely see in campgrounds tow vehicles that I estimate are way over the CCC. Sometimes I will start a casual conversation about their rigs pretending I don’t know much and want to be educated. I eventually get to look at the tow vehicle’s door sticker. I always see on the sticker what I suspected. Way over loaded tow vehicle. Not safe for the family or me driving next to them. Sean Duffy should pass a regulation that all dealerships inform buyers about CCC.
Very good article, most people are more concerned with how much they can pull and ignore how much their truck can stop or manage in cross winds, emergency handling or winding down hill roads.
I still remember my first look at a new Chevy after reading info on towing from – you guessed it – RV Travel among other info. The dealership had two dozen half-ton Chevy’s and every one of them had a 3.08 ratio, listing the max trailer weight at 2,000 pounds. I wanted to buy a 5,000-pound [loaded] travel trailer. The salesman said that I could tow up to 5,500 pounds!!! That was the listing for the 3.42 ratio! His claim was that you could tow up to the next towing limit! I just walked out. The sales manager chased after me, asking what was wrong and I told him what the salesman said. He made excuses – he’s new, didn’t understand the question, I said, “Is everyone trained the same?”
I normally agree the higher rear axle number is better for towing. But have had a 2023 GMC truck with a 8 cylinder engine and 3.23 rear axle ratio, an a 2018 Chevy truck with 8 cylinder and 3.42 rear axle tow just as good as the two Ford F150 2021 & 2025 powerboast engines with 3.73 rear axle ratio tow all as good as the GM’s. The only thing I can think is their transmissions is somehow designed to compensate for the lower gear axles. This would be towing a 8000# TT.
Define “tow just as good”. Do you mean you can go just as fast, stop just as quickly, get the same fuel mileage, or just nothing broke yet?
I have a 2015 Silverado Z71 with the HD tow package. It has a 3:42 rear end and heavier rear springs than the standard 1/2 ton.
11,000lbs tow rating and 1000lb tongue weight.
My trailer weighs about 6200lbs empty and I would guess 7200lbs loaded with an +- 800lb tongue weight. (toy hauler).
I have no problem pulling the trailer. One thing I did do was replace the P rated tires with load range E.
This stopped the tire squat and porpoising while towing.
I also keep my speed between 60 and 65mph. Decreases wind drag and increase fuel mileage.
Is that loaded tongue weight? If not, you are way overloaded! ZERO insurance if you get into an accident!
My 2020 Ford F350 has 3:31 rear end with 6.7L diesel. 475 HP @ 1,050 ftlbs of torque. With my 40 ft Bighorn 5th wheel in-tow, and my wife’s shoes, total weight is 23,584 lbs. For me, personally, the long box, crewcab, dually is a perfect match. . Last summer through the mountains outside temp was 98F. Long climbs were not an issue and water temp hit 214 and tranny temp 211. Well within limits. Temps came down immediately after cresting a hill to 195 which is the thermostat rating. In ideal conditions I run max 62 mph. For me, single rear wheels with a big camper doesn’t leave any wiggle room for safety.
🤣 Does your wife have lots of shoes, or really big feet?😉 Have a great day, Impavid. 😀 –Diane
I agree! I have a Chevy 3500 dually diesel with a 35′ Montana. I pulled it up and down the rockies with zero issues, while others were on the side of the road with their hoods open and steam coming out of their engines! It is so nice to be “over” trucked!
A couple wanted to buy our small fifth wheel, but wanted to tow it with a brand-new, 4wd, 6′ bed, V-8, crewcab Toyota Tundra that they bought the previous week. They wanted to use it to take their 3 teenage grandsons camping! I sent them a photo of my yellow trailer sticker with the 8,645# GVWR clearly shown. I told them the combined pin/hitch weight on the rear axle would be about 1,300#. Then I asked them to show it to their dealer, who had assured them that the Tundra would have no problem towing a fifth wheel. Also, an RV shop had refused to install a fifth wheel hitch the day after they contacted me. They angrily went back to the car dealer, who, of course, offered no refund.
No sympathy. Do your own due diligence!
One more item that need to be considered is the GAWR of the rear axle. I see it on the chart but no mention of how it effects the towing capacity and I didn’t see it in the article. It is fairly easy to be within the payload of the tow vehicle but over the Rear GAWR, which for a single rear wheel truck raises the possibility of also being over the maximum load for the tires, a really dangerous thing. Weight distributing hitches may help with this, but that doesn’t help with a fifth wheel. That’s why GM puts the GVWR, GCWR, RGAWR, Payload, and UVW on their towing labels.
A good rule of thumb is to know there is no such thing as a 1/2 ton 5th wheel. You will be overloaded regardless of the tow package and engine, and you better pray your insurance company does not invalidate your insurance if you ever get in an accident.
