May we suggest that most owners of this king-size trailer (just shy of 43 feet) do not use it for weekend camping trips to their favorite Forest Service campground! Nope, this whale of a home on wheels, the 2026 Puma 421LFT, is meant for living, plain and simple. It can be hauled from place to place, of course. But the Forest River product is really designed to be plopped down in one location and remain there for a while, even permanently.
We don’t even want to think about towing this behemoth down a back road, spacing on some country tunes, and then happening upon a low bridge. Ouch! Bad news!
But seriously, this is amazing in a “Wow” kinda way. We’re pretty darn sure a family with little kids would love, or at least appreciate, this RV with its two lofts, one of which is huge. Mom and Dad could dispatch the kids upstairs, and then snuggle up on the main floor and enjoy a movie.

The video at the bottom of this article is really fun. Hunter, from the RV Hunter, leads you on a quick and entertaining tour of the trailer, explaining what he sees as he goes. We’ve added a few comments as well. But essentially, we are pretty much passing along Hunter’s thoughts to you in this short article.
This RV isn’t for everybody, but there’s very likely a market for it, like there is most any RV, big or small. Here’s a summary of Hunter’s review of this trailer if you don’t want to watch the video (but you should):
The exterior
The Puma 421LFT is stylish with practical outdoor features:
-
Large awning for shaded relaxation
-
Dual oversized propane bottles
-
Drop-frame design for more interior headroom and storage
-
LP quick-connect for easy grilling
-
Dual outdoor speakers and backup camera prep
-
A roof that supports up to 250 pounds for roof work and maintenance.
Interior style
Inside, the Puma ditches lighter tones for a sharp black-and-gray décor that Hunter says feels updated and cohesive. The living area benefits from dual opposing slides, with nearly 6’2” of ceiling height in the slides for a spacious, airy feel. A stand-alone dining table with extension comes standard, though a larger sofa could replace it if buyer demand is strong.
Other living area highlights:
-
Recliners with cup holders
-
Textured glass cabinets
-
Optional table-or-sofa flexibility
Large, functional kitchen
The Puma’s kitchen is spacious, pretty much as you’d find in a typical home. It features:
-
Flip-up island extensions for more prep space
-
Stainless undermount sink with high-rise faucet
-
Waterfall-style solid-surface countertops
-
16–18 cu. ft. Furrion 12V refrigerator
-
Four-burner oven, which Hunter theorizes is big enough for a Thanksgiving turkey
-
Multifunction microwave with air-fry mode
-
Magnetic-latch Murphy pantry for secure storage
Sleeping spaces and lofts
The dual-loft design makes this RV well-suited for families:
-
First loft: It’s tall enough for adults to sit upright in bed when reading or just talking. The beds are simply mattresses right on the floor, so no awards for sleep comfort.
-
Second loft: This space is larger than the other loft, with room for twin beds, gaming setups, or storage bins. You don’t see something like this very often.
Add two full bedrooms—including a queen bed with under-bed storage, outlets, and USB ports. The beds are right up against the wall, so there’s no sticking a foot out over the edge at night while sleeping.
Two bathrooms
Few RVs match this level of bathroom flexibility. The Puma 421LFT offers:
-
Two full bathrooms, both with roomy showers
-
Main bath height: 6’4″ headroom
-
Second bath: 6’2” headroom
-
Ample counter space, drawers, and personal storage nooks
Entertainment
This RV includes some extras:
-
Smart Insignia TV with streaming readiness
-
40-inch electric fireplace for heat and, of course, ambiance
-
Automatic window shades
-
Pull-out sofa for extra guests
-
Washer/dryer prep and hidden kitchen pantry

While I get why they do it, I really don’t like photos taken using a fish-eye lens! The dimensions are distorted.
Bryan, sometimes in the small space of an RV, a very wide angle lens is important. A fish eye may be a little much. I don’t recall a fish eye being used on this video, but a very wide angle lens can provide a similar effect, but usually more realistic.
What, all that and no sundeck up top? 🙂
My 5’2″ wife wouldn’t be able to stand up in a 62″ main bath unless she cut all her hair off! “Dungeon black” is not “updated and cohesive”; It is depressing and makes small spaces look even smaller. That’s why the best interior designers (ie., those NOT in the RV industry) use light colors, bright accents, and mirrors to “enlarge” small rooms. And even a 92″ wide trailer with slides and high ceilings has small rooms.
For a “permanent”, mobile residence (at least mobile before being permanently placed), I would want a true park model with lofts. Then I would have residential–not RV–roofing, siding, flooring, insulation, utilities, appliances, and air conditioning!
I think they meant 6’2″ from what I saw in the video.
Thanks, Donny and Steve. It’s been corrected. Have a good afternoon/evening. 😀 –Diane at RVtravel.com
Thank you for calling attention to the RV and video, RV Travel! This seems to present a real problem. The manufacturer is Forest River, so, given their history, the probability of this being recalled, or there being considerable warranty claims, is high relative to the industry. So, I wonder how many they’ll sell? I guess we’ll see. Moving it once is bad enough, given the size, but repeatedly? Yikes! Have a great weekend and safe travels!
My first thought, why only dual axles? Should be at least 3 or 4. Tongue weight of almost 2k.
Will need at least a 450 or 550 to haul it. Hope they put larger brakes on the two.
I bought a new Forest River product. Dual axle. The manufacturer never adjusted the brakes before it went out to Camping World to sell it. I drove around burning through 1 of 4 brakes, for way too long. After taking on an 8% grade and almost dying, I took it to an independent RV repair place. 1 brake was metal to metal. 3 were untouched. You bring up a great point! Poor engineering and lack of quality control are widespread in RV manufacturing. They justify it by saying the warranty takes care of this intentional shortfall. BS! It’s a dangerous practice and the way the dealerships delay doing the work, even a 2 year warranty isn’t adequate. Just saying.

What I really don’t understand is the ratio of sleeping space to living space (pretty high!). With the ability to sleep so many people, where in this RV are they going to be when they’re not sleeping? Only the double recliners and the dinette for seating in the living area (or, if you replace the dinette with a sofa, then no more seating space, plus a challenge to eat, no?) Also, I wonder if it’s a good idea to have slides on a unit that most likely won’t be moved, and might likely sit opened up permanently.
