Stayed at Fishing Bridge in 2012 with a 27' trailer. Will do it again next time for the full hookups and central location. Yellowstone is huge and you spend all day driving around seeing stuff. We were at our site very few daylight hours. The camp store is decent and there is a fuel station there with diesel--even an auto repair garage. The campsites are small and would be tough for a motor home, but no problem for most travel trailers. Our best memories were the buffalo wandering through or watching the German tourists drain their black tank.
