I'm not an "expert", have had a Jayco pop-up for years and a Jay Flight 26BHS for two years. Things I think I've already learned:
RVs are for the most part pretty cheaply built so as to be as light as possible. From lots of shopping for used units I believe RVs don't age well, especially if stored outdoors. Their systems are numerous and not particularly simple so plan on learning a lot. I liked the dealer I bought from but I learned more about operating the rig and the hitch system from YouTube. The first time out in my Jayco 26 the awning failed to work and the a/c unit on the roof blew out with a loud boom and a cloud of vented coolant. I traded it on another unit and it has worked fine, so maybe quality unit-to-unit is unpredictable. When they say "1/2 ton truck towable" they mean at 30 mph, not highway speed or up a mountain.
For all that, we've enjoyed the unit and Jayco seems to be overall a good choice. We're glad we bought it. I'm just glad I have a place to keep it stored inside.
