Today’s RV review is of the 2026 Grand Design Reflection 342BHTS. I specifically sought out this unit after reading Russ and Tiña De Maris’ article about the “worry-free” features in new Grand Design offerings. However, this doesn’t have that.
What we do have is a very large travel trailer that has a higher-than-average interior ceiling at 7’ and a separate rear space that can be a bedroom or just a place to retreat. That would be handy if you and your spouse have a disagreement or someone was a sore loser in Monopoly.
This has one feature that, to me, is quite troubling and a few things that are head-scratchers. What are those? Let’s dive into it.
How the Grand Design Reflection 342BHTS is built
After reading Russ and Tiña’s article, I got all excited about improvements to Grand Design products, but what I looked at is one of their more mainstream lines, the Reflection. Apparently, the new roof structure and the improvements to the suspensions aren’t found here, which is unfortunate. Perhaps it’s coming in the future. Let’s hope so.
What we have is a very, very large travel trailer and one that Grand Design does a good job insulating. The company states that this trailer is usable from 0°F–100°F. How the company accomplished this includes insulation, but the underbelly is also heated and enclosed with a radiant foil barrier.
I do like that Grand Design has moved to Goodyear Endurance tires. However, they’re still not offering a tire pressure monitoring system as standard and, to me, this is a huge safety challenge. But they did include anti-lock braking, which I think is a big plus.
The suspension on this is a simple leaf spring arrangement, but with a CRE 3000 suspension dampener package. I suspect a trailer this large might end up spending most of its time at a seasonal site, which makes sense.
Wall construction
Another thing that surprises me about Grand Design products, including the more premium units like this one, is that they’re still using lauan in the wall lamination. So many of their competition have moved to man-made substrates like Azdel. When I questioned Grand Design about this, they said, “Isn’t it better to just keep the water out?” Well, that’s the goal. But if the water gets in, and it often does in RVs, now you’re doubly hosed as lauan gets heavily damaged by water.
I do like that Grand Design has placed a shut-off at each major fixture for the plumbing, so a leaky faucet isn’t going to end your getaway.
This is a 50-amp RV, and there are two air conditioners standard here.
Fuse box blocked
The lack of a TPMS is one thing—but I want to point out that the fuse box for this is blocked by the slide room when that’s closed. Now, this does have a rack-and-pinion slide system, which is the easiest to override, in my opinion. But how do these kinds of goofs get by designers? Imagine blowing a fuse, and now you have to figure out what to do about that while the slide’s blocking it.
Honestly, the lack of a TPMS and this fuse box thing would have me shopping elsewhere. But that’s why I want to share these details in these reviews. Hopefully, you’re making a checklist for your next RV shopping adventure.
Oh, and one more thing. The cargo carrying capacity on this trailer is about 1,000 pounds, which seems like a lot until you think that you can sleep up to eight people in this trailer. That means they’re bringing all their stuff, in theory. And, if you carry the allotted 54 gallons of water, now almost half your cargo carrying capacity is already gone.
Inside the Grand Design Reflection 342BHTS
This is a nice space, and the higher-than-average ceiling of this rig, along with the opposing slides, really make it feel more open.
In the kitchen is an island with some good storage built into it. There’s even a pair of pet dishes in a drawer at the base of the island. The stove, microwave, and fridge are all good-sized and reflect a premium feel in RV appliances.
There is a four-place dinette and a couch here, with that couch featuring a center armrest so it serves almost like a theater seat. That makes sense since it’s across the aisle from an electric fireplace and a TV on a televator.
The bulkhead storage at the front of this space is outfitted with a power outlet and a provision for those who use Starlink. Many of the RV builders have really adopted Elon Musk’s internet from space system, and that’s a good thing.
Sleeping in the Grand Design Reflection 342BHTS
There is a room at the very back of this RV that has a two-person hide-a-bed. This could be a nice getaway room if you don’t have the need for sleeping more people. Above the couch is a swing-up bunk, and across the space are drawers and a provision for a TV.
Above the drawers is a larger bunk space. Again, if you aren’t needing more sleeping space, this could be storage. Just keep in mind the poor cargo carrying capacity of this trailer.
Up front, there’s a bedroom that features a proper queen-sized bed with storage on either side as well as below the bed.
There’s also a closet in the front bedroom that could either be used for more storage, or you could add a stacking washer and dryer to this space. Oh, know that even a combo washer/dryer unit will set you back almost 200 pounds. Now you see why I keep harping on this reality.
Final thoughts on the Grand Design Reflection 342BHTS
There’s a lot to like about this trailer, but the downsides are significant enough that I would shop elsewhere. For example, Alliance has a similar floor plan in the Delta 321BH that has twice the cargo carrying capacity, uses Azdel in the wall build, and costs almost $10,000 less. Rockwood’s Ultra Lite 2918BH also uses man-made substrates, has a torsion axle suspension, a vacuum-laminated roof build, and comes with tire pressure monitoring.
This just shows that there are always choices in the RV space, especially when there are some pretty glaring deficiencies in a model that other RV companies gladly avoid. And that’s why I keep writing these reviews—hopefully, shoppers and RV decision makers will see this and keep moving forward.
My thanks to Josh from Bish’s RV for the video and photos in this article.

Great review, Tony! Please keep calling out the manufacturers when they do dumb things! (1000# cargo capacity? Really?)
Picture #5, silverware drawers:
What makes them think they know how one wants to arrange those things? Newmar does the same thing putting huge dividers in that are just in the way of using trays that meet individual needs.
When we got our new-to-us ’21 New Aire a year ago I posted on IRV2 about this asking what others did, since the dividers in mine were permanent. Based on the dozens of responses, I’m not the only one that just wants a drawer without preconcieved dividers!
I found it quite amazing that this trailer only has a 1000 pound cargo capacity. Seems light for a trailer this large. Makes me wonder what kind of camping the trailer is designed for.
Our Sprinter Class C, notoriously short on cargo capacity, has more CCC than this 38′, 8-person, travel trailer! The only way this thing works is to tow it without any fresh or waste water in the tanks and only dishes, pots and pans, and bedding/linens in the cabinets. After setting it up on a seasonal, FHU RV site, you then unload clothes, groceries, and the family from the tow vehicle into the trailer, connect it to a 50A power pedestal, hook up the water and sewer hoses, and pretend this travel trailer is a destination trailer. And hope all that added weight–food, clothes, people, waste water, etc.–doesn’t break something or bend the springs. No thanks!
