Having a HTT is a different game entirely. We had a ROO 23SS, but when the bunkends are dropped, about 4' is added to both front and back. The trailer itself was actually 20+, but I always reserved sites based on 30'. I do most of our reservations online and the majority of state parks, COE, etc have pictures of the sites, which help a lot....you can see if trees or other are going to be a problem. We found that our fav site at our fav SP and was a snap to get into with the ROO, is now a PITA with our 2604....lost maneuvering space and the slide is about 1/2 again as deep as the one on the ROO, so shifting over. Folks with 3 bunkends in a HTT really do have to look for trees and utilities on that side.
