I’m afraid I don’t know. we were in loop E and the spaces seemed plenty long enough. The other loops are smaller sites. I’d call them.

I found the rangers to be very accommodating when it comes to problems with the campsite. We were in a 30 foot site with a 30 foot motorhome and had room front and back.

I stayed at a 50’ site while there with a 20’ truck and a 27’ trailer and I had about 3’ of reasonable wiggle room to work with before we were hanging off the pad. I imagine you might have that much, but you would have to position your rig and trailer such that you can park alongside your hitch and get another 2’ or so. You might not be able to. It’s iffy for sure, and they will definitely notice if you hang off the pad or have a tire in the mulch.
