I came from a 29' Travel Trailer, a Jayco Jay Flight 26BH so I needed room. The Aliners were just to small and crowded with their A frame roof. Europe has hard sided, flat roof campers but not here in the USA.
I went with a 14' box pop up so I had the beds for my family. I missed camping in a Pop Up when I had the Jayco Jay Flight. Felt I may as well stay home or do day trips as it wasn't like camping but staying in a hotel or cottage. Now I get to hear the wildlife at night and can sleep under the stars with all the windows open.
Back to my glorified luxury tent with all the amenities!
