Keystone Reign 15RBS review - love it or loathe it?
Today’s RV review is of the Keystone Reign 15RBS travel trailer. The Reign is a small, single-axle trailer with no slide. But what’s truly unique about it is how it’s built and configured. In fact while the construction is something we hope to see much more of, the interior is going to be very polarizing. How so? We have the story here.
How it’s made - a different construction technique
This is indeed a laminated wall much like you’ve seen on a lot of RVs but it’s also very, very different. We have an article on RV construction types here.
RV construction types
Typically laminated RVs are built with an aluminum skeleton. Then insulting foam is placed between the aluminum studs. There’s an outer substrate layer and inner layer then glued to that and, on the outside, a finishing layer which has typically been fiberglass.
Depending on the company, the inner substrate and inside layer can be wood product called Luan or a man-made product such as Azdel. Know that Azdel is a brand name, like Kleenex. Recently the rights on this ran out so other companies are making very similar products to Azdel but Azdel did a great job of marketing their brand.
Anyhow, this is different in that the outer layer of the laminate is a sheet of aluminum and that’s where much of the structure comes from. There are no studs in the walls but there is an outer substrate of human-made materials and the inner walls, too, are human-made materials.
One of the big advantages of this type of build is that it’s strong and light, much like traditional laminated walls. But the aluminum studs are a poor insulator so there are times you can literally “see” them if the temperature is just right.
So, not only is this a strong built but there are fewer thermal losses in theory.
Another plus is that the exterior walls, being a big sheet of aluminum, can be painted. Yes, so can fiberglass, but it’s going to be more common with these just based on the supplier. And that’s what you have here - the green tint of the exterior of this is actually a paint so it will arguably look better longer. Nice.
Right now the only other example I can think of where this is being done is with Brinkley RV in their new Model I series.
In addition to the walls, the floor in this is also a laminate which Keystone calls HyperDeck flooring. I know some flooring laminates haven’t done well in long-term use but I haven’t heard any issues with this solution from dealers whom I keep in touch with. The benefit of this is that it’s lighter than wood flooring and, like the wall laminate, is essentially impervious to water damage. That’s a good thing.
More build features
In addition to the very unique wall construction know that this is built on a B-A-L frame. The significance of that is that these frames are bolted together with huck bolts rather than being welded. The company claims these frames are stronger.
I really like that this trailer rides on torsion axles, rather than leaf springs. Have you seen our story and video about riding in various trailers with different suspensions? It’s a big deal when an RV maker uses a better suspension as it means less vibration and harshness in your RV which can help it last longer.
Another interesting thing I noticed is that these use more traditional fold-out steps rather than the solid steps that are so common nowadays. Oh, the solid steps are an option, but there are a lot of reasons why we don’t like them. A lot. We’ve detailed those in the video with this article.
Something I saw on the prototype, which may not be in the final production models, are two dump connections. That seems really odd on such a small trailer and it remains to be seen if it’ll continue into production.
Something else we saw on the prototype was some very bright LED light bars that looked like neon lighting down the sides of the front of the rig, down the underside and up the back. These red and green lights are pretty bright and I can see this being an issue if they’re left on in a campground where people go to appreciate the night sky.
I can’t be too critical of these lights as I’m having them added to our new trailer, but the objective will be attention-getting brake lights. I won’t leave them on at night, I promise.
Lastly, this uses frames windows which I like quite a bit because the glass actually covers the seal which means a bit less maintenance and longer life.
Something Keystone is also known for is their wiring. Unlike most RV companies who simply empower line workers to pull wire as needed, Keystone intentionally wires their trailers with specific wiring colors. When I worked at a dealership we had the fewest issues with Keystone products in wiring and, if we did have an issue, the intentional wiring coloring made it really simple to diagnose. Smart.
What’s inside the Keystone Reign 15RBS
I suspect you’re either going to love this little trailer or loathe it based on a couple of things, so let’s get those out of the way.
The first of those things is the Murphy bed, which this has. By day you have access to a couch which jackknifes easily. A platform comes down and there’s a tri-folding mattress. If making the bed is your issue with Murphy beds, you should know about the RV Superbag. We’ve been using one of these since we had our first Rockwood which had a Murphy bed and it’s held up very well over the years.
But the other thing I saw was that all the storage spaces were open. There was not one cabinet door to be found - everything was wide open.
Adjacent to the bed there are taller closets which open into the space the bed occupies but, again, no doors.
I know building and mounting doors is an expensive process so I can see the reason for this, but it’s also just weird. If you don’t want your stuff flying around while you drive perhaps more bungee nets would work but they’re not provided in most of the openings so there ya’ go.
Know that it’s not just the bedroom and kitchen that don’t have cabinet doors, the bathroom doesn’t either.
More interior features
This does come with a small electric fireplace which I wasn’t all that impressed with the first time we had it, until I realized how nice it was to have a silent electric heater at night. You can turn off the flames and just let the fireplace act as a heater so if you have full hook-ups, this is often what we do to heat our trailer in the shoulder seasons.
The kitchen in this trailer consists of a two-burner in-line propane stove top, a round sink and a convection/air fryer microwave. I did see some prototypes with an induction cook top and I suspect there were thoughts about making this an all-electric trailer, but the actual production model we saw had a propane cook top and propane furnace.
Bed bonanza
While you might not like the Murphy bed, it’s not the only disappearing sleep surface in here. There is a two-person dinette here with a pole-mounted table that can convert to a bed. I don’t have dimensions for this, but I suspect it’s more for the smaller travelers.
Another option is a flip-up bunk above the dinette. I didn’t see that in person but it’s a nifty idea.
Bathroom in the Keystone Reign 15RBS
While this is a very small trailer it has the advantage of having a bathroom that spans the width of the back of the trailer so it is rather spacious. You would certainly have no issues accomplishing any task you went in there for with lots of space.
I like that Keystone included a high-performance vent fan in here and that fan has a light.

Boondocking and travel access
Keystone has been a real pioneer in their solar offerings with what the company calls SolarFlex. Essentially it is a really good way for the company to offer a variety of solar packages in their RVs starting with a simple 220watt panel and the infrastructure to add an inverter if you chose to.
The brilliance of this is that Keystone worked with dealers to provide the upgraded pieces such that, if a dealership installs the Keystone-supplied parts, the whole installation is still covered by Keystone’s warranty.
However, some dealerships wanted no solar whatsoever and I am always a fan of options. Put a channel on the roof of an RV and I’m a happy lad.
But this trailer comes with what Keystone calls SolarFlex-ready. I suspect that that means that the wiring and ports are in place but no solar is included standard. I requested clarification but, as usual, I waited too close to the deadline.
There is a SolarFlex 220 factory option which includes the single panel as well.
Other than that this little RV doesn’t do anything exceptional for boondocking such as a Shower Miser system but you could always do well with one of the Geyser Shower Systems that we like so much to save water off the grid.
Final thoughts about the Keystone Reign 15RBS
Frankly, I like what Keystone has done here. Not just the construction techniques but just going out on a limb with styling of this little trailer. It’s definitely going to stand out at an RV park and not for bad reasons.
I do hope owners recognize how intrusive the exterior lighting can be and don’t inflict it on other campers but we can only cross our fingers when it comes to being a good neighbor.
I think the interior is very polarizing indeed but it’s certainly attractive. However all those open cubbies are definitely not going to look as good when stuffed with camping gear so we shall see how that plays out.
But, overall, I think Keystone has really done a great job with this little rig. That metal exterior is going to likely result in these trailers remaining attractive longer than most so it’s a good thing that, at least in my eye, it’s a nice looking rig.
