RV review - 2026 Rockwood 2108RB
Review of the 2026 Rockwood Mini Lite 2108RB
Today’s RV review is of the new-for-2026 Rockwood Mini Lite 2108RB. This is built on the smallest of the Mini Lite designs and is a really unique bit of packaging that’s mostly positive. Know that the Flagstaff 21SRB is identical - we even have an article about why RV builders make twins.
Rockwood (and Flagstaff) have three basic “boxes” that they build the Mini Lite and Micro Lite in - the 2100, the 2200 and the 2500. Most Rockwood-Flagstaff RVs are built in the largest 2500-series box including our own Rockwood Mini Lite 2506FK model which measures 26 feet in overall length. This model measures 22’ 2” in overall length and features a single slide.
Start at the road with the Rockwood Mini Lite 2108RB
Anyone who regularly reads these reviews will know that I advocate looking under any travel trailer or fifth wheel before ever stepping foot inside. The reason is that RV makers do a good job of making RVs pretty inside but what really sets one apart from another is in how they’re built.
For example, the Mini Lite line features American-made Goodyear Endurance tires with built in, banded, tire pressure monitors like most vehicles have nowadays. Rockwood also fills the tires with nitrogen but then also puts balancing beads inside to help them stay in balance.
The suspension on these is a Dexter torsion axle.
Essentially as your RV is being towed down the road the fewer vibrations and harshness that get transmitted from the road to your rig the longer the RV itself will likely last. This tire and suspension combination is one of the better ways to minimize road harshness.
Rockwood uses a through-frame rack-and-pinion slide in this model which I also think is the best type of slide mechanism. They tend to have fewer issues and you can easily override them if there is an issue.
As for the walls themselves Rockwood uses a lamination process that vacuum bonds the layers together. The outer wall is fiberglass but then under that is a layer of human-made material - we’ve all become familiar with Azdel but now other manufacturers can make this product but it’s essentially the same waterproof material. Then there is a welded aluminum structure with block foam insulation and wall board. Rockwood is also using a better glue than most - all these little details really do matter.
And, see, we haven’t even gone inside yet!
What’s inside the Rockwood Mini Lite 2108RB
Okay, now that we’re inside one more bit of nerdy talk. Rockwood uses a welded aluminum structure for things like bed bases, dinettes and that sort of thing. It’s lighter and stronger than wood although it’s more expensive.
When you first step into the trailer you’ll see a small dinette at the front and then a sofa over in the slide room. Something I love about the new dinette table that Rockwood is using is that it can move front-to-back and side-to-side a few inches so those of us who displace a lot of water in the pool still have room to be comfortable. It’s fat folk friendly! That table also can be pushed up and down and will stop where you like so you could have it be desk height or table height or mash it all the way down to make a day bed.
But then once the table is down you also have a Murphy bed here and Rockwood does the best Murphy beds in the business, period. End of story. No debate. Why?
These are all one piece so no requiring a bendy mattress to make this work. For us this was a good solution and that’s where we learned about the RV Superbag to make this even better.
The bed in here is a “short queen” at 64” x 74” which is what we had in our first Mini Lite. From what I could tell you could leave the bed down all the time and be able to bring the slide in and out although I’m not certain and I codlin’t try my theory at the display I saw this at.
Around the bed are closets on either side as well as overhead cabinets and the cabinets overhead feature door hinged at the top with springs that hold those doors up. Nothing like trying to hold the doggone door up with one hand while spilling all your sock on the bed with the other and then saying a word your mom told you not to say.
Since there’s that mini dinette at the front there’s a theater seat in the slide of this RV. This is a lot of good seating in a relatively small trailer.
Kitchen in the Rockwood Mini Lite 2108RB
As much as I was impressed by the amount of seating in this trailer I was equally impressed by the kitchen here. There’s a full-sized (10.7 cubic foot) 12 volt refrigerator and I shared how much I like these new fridges and how efficient this particular model is in this story.
Rockwood also uses a three-burner propane stove along with the larger-than-average 21” RV oven. I have the same oven and, yes, we’ve used it for all kinds of things including pulled pork, roasted veggies and more. The larger size of these 21” (vertical) ovens really do make a difference.
There counter top is an “L” shaped unit with a sink sort of facing the Murphy bed. For a trailer of this size the counter space ain’t half bad. To make things more useful; however, there is a counter top extension and the counter tops in this trailer are solid surface which tends to last longer.
Bathroom in the Rockwood Mini Lite 2108RB
The bathroom in this extends the full width of the rear of the trailer which means you have good space for what you need to do here. There’s a porcelain foot flush toilet and a decent linen closet along with a rectangular sink.
The shower is a rectangular unit that incorporates a feature called the Shower Miser which redirects water into the system while you’re waiting for it to get hot in the shower, thereby not wasting water if you’re boondocking. We use this feature a lot in our own trailer.
Something I really like is that Rockwood still uses the six gallon traditional gas-electric water heater with a tank. I know lots of RV companies are bragging about their tankless water heaters but these are often a lousy solution. Why?
Tankless water heaters work based on demand. If they sense that you’re requesting hot water they turn on the burner and heat the water as it goes by. But if your water pressure is low, it may not trigger the burner. And, if you’re at high elevation, that may not allow the burner to ignite.
And you only have propane to heat the water, no electric. But the reason RV companies like these units is that they’re relatively easy to winterize and they’re inexpensive for RV companies to purchase. Rockwood tends to favor things that serve the customers better like 21” RV ovens, welded dinette bases and gas-electric water heaters with a tank.
Rockwood has also recently upgraded their plumbing so that they’re not using the troublesome clamp system on flexible lines that has been prone to failure. The tanks on these are supported so you can travel with water aboard.
Final thoughts on the Rockwood Mini Lite 2108RB
Is this RV perfect? Absolutely not. For example I think is goofy that there’s a windshield and a Murphy bed - you have a windshield when you don’t want it at night but the bed being stowed blocks the windshield by day. See, goofy. But at least on all the windows Rockwood uses roller blackout shades which really work well.
