We had a popup for 17 years and loved it. Took it to every state in the northern half of the US except Alaska. We loved that we could push it around to get the optimal position within campsites, and loved the simplicity of it - no water system (we disabled it after it leaked the first year we had it), no battery, no weight distribution needed, etc. (Brakes would have been good; it didn't have any.) However, as we got older, an enclosed TT was in order, and we are now happy to have that (especially now that we live in bear country).
BTW, we downsized too, going from a small (18') Class C to the popup, and recently from a large TT to a medium-sized TT.
Enjoy!
