The cargo carrying capacity goes down with the longer length. Although that may not be an issue for you. The towing capacity -Ford vs Chevy is different. The extra room is nice. We went with a longer one because the shorter ones did not have a couch. The main seating was the dinette. And we did not like the corner bed in several that we looked at-wanted to be able to enter from the sides instead of crawling in from the bottom. We really wanted a shorter C, but could not find one with the features that we wanted so we had to go longer. Gary
