I've seen full-sized buses in this campground with some room to spare. This is a first-come-first-served campground and I'm sure the host will place you accordingly. Of course I cannot guarantee anything, but we've used a 35ft trailer on there and had plenty of room to fit our tow vehicle at the front of it and another SUV behind it. Remember, all these sites are pull-throughs that run parallel to the road, which gives you a lot of room. You may not be able to put your trailer in the middle of pull-through, but will most likely fit.
