Today’s RV review is another debut: the 2026 Alliance Delta Solo RB152 travel trailer. This is the smallest RV that Alliance makes in the form of a single-axle, no-slide trailer. In fact, this is the same layout as the first new trailer I bought, a Rockwood Mini Lite 1905S. Alliance has done some things I wish I had had on my own trailer. But there are also some things I liked better in that trailer. What are those?
First of all, the new “Solo” designation on the Alliance Delta line refers to these new single-axle models from the company. As I write this, there are three choices in this line: the one we’re looking at here and then two slightly larger models, both of which have slide rooms.
My reason for choosing this one goes back to my having this floor plan. If you ever think a small, single-axle trailer is just for short jaunts, know that we dragged ours all over the Western U.S., including making a complete journey on Route 66 from end-to-end. That little trailer went boondocking in the desert and mountains, and we would spend months on the road at a time.
Yes. It was a bit tight for two people, but it was the key to fun adventures.
Start at the road with the Alliance Delta Solo RB152
As mentioned, these are single-axle offerings from Alliance, which some people seem opposed to. Typically, I see the reason given that if you have a flat, you only have one tire. But, honestly, if I have a flat in my truck, that whole corner goes down because there’s only one tire at that corner.
And you still have to replace the doggone tire. So use good tires and a tire pressure monitor, and you should be fine.
On the subject of tire pressure monitors, this is prepped for the TST tire pressure monitoring system, but doesn’t actually come with it. Get it. Don’t hesitate. Get it. The tires are Goodyear Endurance tires, so we’re off to a good start.
This does use the Norco BAL Huck-bolted frame, which that company claims is stronger than welded frames. The trailer I had, had this as well. I was able to split the frame finally after plenty of driving, with the final trip involving one heck of a drainage ditch and an inattentive driver (me). My advice would be to keep an eye out for rust, which I didn’t do.
Underbelly is enclosed and heated
Something you usually don’t find in this type of trailer is that the underbelly is enclosed and heated. Interestingly, the way this trailer was designed, the entire floor of the trailer sits above the wheel. The wheels don’t actually intrude into the body of the trailer, but that also makes it taller.
One of the things I really have liked about Alliance products is that they have a plumbing shut-off at each fixture. Therefore, if there is a failure, it won’t end the camping trip. This continues that. In fact, there are a lot of rather high-end features in this smallest of Alliance Delta trailers. So you get a smaller, more nimble rig without sacrificing some of the better quality features.
Stabilizer jacks
While we’re underneath, take note of the fact that this has four stabilizer jacks, one at each corner, plus the power tongue jack. Those stabilizer jacks are installed at an angle to the chassis. That offers better support, according to what I have been told.
Also, there’s a wide ladder on the back, so it can also be a towel rack. There are handles on the roof to make it easier to get up there once you’ve reached the top. Nice touch!
What’s inside the Alliance Delta Solo RB152
Even though this is a short trailer with no slide, these are actually pretty usable inside. Part of that comes from the use of a Murphy bed at the front. For all of you who don’t like Murphy beds, know that you don’t have to put this one away. However, leaving the bed down will severely hamper the trailer’s usability.
With the Murphy bed stowed, you get a two-place sofa with a drop-down center armrest. Nice.
There’s also a two-person dinette here with a table that’s mounted to the wall so you don’t whack your knees getting into it. This table does mash down, so this space can become a bed. But spouses, you might want to watch your P’s and Q’s so you don’t end up here; it’s a space better suited to the wee ones.
Funny thing: We were evacuated due to fires in the community when we had this floor plan, and our poor friend slept on the dinette table during the evacuation. She found a better solution in short order.
Kitchen in the Alliance Delta Solo RB152
If you’re the next ultra super duper chef and are looking for that expansive canvas on which to practice your gourmet goodies, this might not be the place. But it’s absolutely fine for a trailer of this size. Alliance has employed the two-burner in-line propane stovetop and a convection air fryer microwave, as well.
I like the quality of the countertops in this rig. Plus, there’s a flip-up counter extension, which is something I finagled in my own version of this trailer. This official version is better.
Alliance still uses the 10.7-cubic-foot, 12-volt refrigerator in here, which is larger than most. There is a decent amount of cabinet and drawer space in this rig.
Bathroom in the Alliance Delta Solo RB152
One of the things that sold me on this floor plan was the bathroom, which spans the full width of this rig. Alliance uses a porcelain toilet and the shower, at 30” X 36”, is also decent. There’s a series of cubbies as the linen closet. The stainless steel sink sits in a solid surface counter. Lots of nice touches.
The one complaint I have is that the vent fan is one of those noisemaker 4” fans. However, I found a new gadget, this Maxxair Maxxfan Pivot fan, and I’d swap that in in a heartbeat.
Final thoughts on the Alliance Delta Solo RB152
When we were trailer shopping for our first new RV, I wanted a small, single-axle trailer with a Murphy bed. What I found was that many of these were indeed small with narrow bodies, but the one we honed in on offered a full 8’ width. That’s unusual. But today’s trailer is also a full 8’ wide. Nice.
Something I am much more keenly aware of nowadays is that people get obsessed with the gross weight of an RV and the towing numbers that vehicle manufacturers use. But actual tongue weight, how much of the trailer your tow vehicle has to carry, is often an even more important number.
Towability
Further, the larger the front of a trailer is, the more it can limit what can tow it. So this trailer might seem ideal for some mid-sized pickups or SUVs. However, I’m not sure, what with the taller stance. If this is something you’re considering, and it is a nifty little rig, I would see if the manufacturer of your tow vehicle has a rating for frontal area.
I don’t know if it’s just nostalgia or the recognition of a good design, but I really like the way Alliance packaged this new offering.
While the Murphy bed does use a mattress with a hinge, that preserves a decent front pass-through storage compartment, so there’s your tradeoff. Overall, though, this design shows that good things do come in small packages.

Good review, Tony. This is a well designed trailer. And great tank sizes for dry camping.
Looks like a well thought out design with decent quality as rvs go. But neither you or the video mentioned what the black item in the pass through storage compartment is?
Hi, Denny. I think Josh referred to it in the video as “welded aluminum cage work”– whatever that is. So I quickly went through the video from Alliance RV and it showed it from both sides but he didn’t explain what it was. But I’ll bet Tony knows.👍 Have a good night. 😀 –Diane at RVtrvel.com
Great question and it’s a huge deal so I’m remiss. It’s an access bay to the back of the water system so you can shut-off individual fixtures. I would have loved to have had this feature in my own camper and I think it’s something that sets Alliance products apart in a very good way.
Thank you for the review, Tony! This may be just the thing for someone wanting a base of operations for hunting or fishing in addition to being a great single-person or couple’s RV. Have a great day and safe travels!
