We just returned from the RV show in Belleville. There were a lot more travel trailers than fifth wheels on display. I did see a familiar looking logo hanging in a Sandpiper fifth wheel.
There were a couple of units that had features that I’ve never seen before. There was a V-Cross with the optional powered drop down bunks that were stowed over the couch and dinette. I believe it was a 29 VCRLS model. The bunks didn't fold down, instead they raised and lowered vertically. That seems like a great idea for grandparents that only take their grandkids camping a couple of times a year.
The other unique thing was a bedroom slideout on a fifth wheel. What was unique was the front cap was the slide out. I really couldn’t see much of an advantage to that design because the bedroom still looked very small. Personally I can see this feature disappearing in a year or two.
