The missus and I are looking for a 5th wheel. We plan to hit the road a couple of months in the spring and again in the fall every year. So far, I haven’t been able to find exactly what we want, so ...
Lots of wants there. The biggest one is "fully usable with slides in". How many of them are actual needs? Why does the dinette need to be usable with slides in? Understand the TV thing. So many have TVs at awkward angles.
Hope you don't want all this in a 30' package. Ain't gonna happen.
Doing a few big shows is a good idea if you plan to buy new. Nothing wrong with buying lightly used & almost new too. Search the used listings online. More floorplans there than any show.
