Note Towed vehicles on a class A,B,C, need not be counted in "Total length" if you have two people... WHY: You "Drop" the towed outside the park and drive 'em in independently. Thus corners you have no towed.. Only the site.
YOU may need a second site or need to park the towed at the restroom or some such though. I'll do that Sunday (park the towed at the rest room) while I finish packing and bring the RV around,, WHY, cause if I do it that way there is a real tight corner I can make and cut a good half mile of park speed bumps off my trip.
