Here is a Basin Campground map that you may find helpful.
The parking slot for 53 is long, but is also shared with 50. Plenty of room for the trailer, but the truck may be tricky without infringing upon the other campsites. Good diplomacy will go a long way though. As was suggested in your other thread, perhaps try contacting Mirth2 via Private Message and ask him. He is a camp host.
