With our ROO HTT, it had a box 20'+ without the beds deployed. When the rear bunkend was out, add about 4'. The total B - B length was around 24 with the rear not deployed. I always said 30'. Our 2604 had a box truly 26'4" and B - B was right at 30. I still said 30 and sometimes 32' depending on the knowledge I might have about the campground. If you have a deep side slide, be sure to ask about trees on that side. With the HTT, we found some sites that were a decent fit until you tried to drop the rear bunkend and found a tree in the way. Most times I reserved online and could sometimes see a pix of the site. When in doubt, I called the CG to ask about those specifics.
