You should be OK with that rig; length is OK, height not much different from some of the taller 5ers. I've stayed at several CGs that were near race tracks and it was not unusual to see some of the custom car haulers (living space in the front, dual elevated car carriers in the rear) pull in for the night or the week, depending on the race venue. I spent the week once at a CG, near Phoenix if I remember correctly, and that fella had a flight simulator (actually three) in a live-in trailer; a regular 53' pull and he went from air show to air show on the road with his rig spending the downtime at CG's on the road from show to show and downtime in between shows. Was really a nice rig and we spent many hours visiting with him while he "prepped" and "overhauled" the simulators prior to an upcoming air show. He actually offered to sell it to us as he was looking to "retire" soon and he could tell that I knew the electronics (retired CT/MRI research), but, I quickly informed him that I was retired and wanted to stay that way! Moral of the story...there are a lot of different rigs out there and most campgrounds can handle the size of what you are talking about. The issue with "customs" is whether they look well done, or a "back yard special" and the design of yours should garner a lot of "gee whiz" and not "oh, no(s)!"
Please, I'm with others here...pictures would be greatly appreciated when you get the rig assembled. I always appreciate the "out there" monster customs, the huge dedicated "assault campers", etc. The imagination of man is a wonderful thing (most of the time!).
