You should be fine by backing the truck in next to the camper. If you have a curb side slide on the front of the FW, you may have a problem.
Remember you will need to keep the tires on the pavement but you can let the rear of the trailer hang over the back of the site unless you have trees blocking the way. If you can get a site on the top of the hill in the back, you should have plenty of room.
I've stayed there with a 30' TT towed by a 22' vehicle, a 35' FW towed by a 20' vehicle and my father was there with a 37' FW towed by a 20' tow vehicle. Never had a problem, but then again I go out of season so do have a couple of sites to choose from.
