I have a small TT, a KZ 17RBS. Its about 19' over all length. I had 2 pop-ups prior to the KZ, a soft side and a hard sided Jayco A-Frame style. I really liked the A-Frame pop-up. I could literally set that camper up by myself in 2 minutes.
Some people like all the conviences of home when they camp. And will spend most of their time in their camper. I'm more of the outdoors type and only sleep and poop on mine. 99% of the time i use the campground showers.
To each their own! But i'd have no problem going back to an A-Frame style pop-up. Aliner came out with a new "off road" one that looks interesting...
