We pulled our popup with a Honda Pilot, and it worked like a charm. I had to run the wiring for the 7-pin plug and a brake controller, and add a tranny cooler. It was a 12'box with a dinette slide.
You knew it was back there, but it handled fine. I can't believe with all the CUV's, and minivans that pops aren't selling like crazy. I bet the poster above is right, no one knows/wants to do anything that takes effort. I'd say lots of people that do things themselves already have a truck, so they go with a hardside.
We had 9 great years in our pup before we went to a hardside, about half the trips we pulled with the pilot, and the others with my 3/4ton truck.
