We like to camp within park boundaries and in Yellowstone I was told by the camp rangers (?) that truck and RV must fit on the pad and there is no overflow parking and NO parking on the grass as they would tow (or ticket?) my vehicle. We ended up at Fishing Bridge as it was the only one that could/would fit our, at the time, 34' 5th wheel.
A quote from Fishing Bridge website:
Fishing Bridge RV sites will accommodate a towing unit and a towed unit side-by-side. For example, a 35-foot site would accommodate an 18-foot truck and a 35-foot trailer (unhooked) side-by-side in the site. Adjust for slide outs.
We got a 35' site. The back bumper was touching the backstop posts, the front cap was even with the front of the site and, with our slide outs, our truck barely fit on the side. Had to let the wife out 1st, then back into spot.
So my point is ... call and ask.
