i pull my 43 foot 5th wheel with a ford dually and haven't had a serious problem as of yet. I do make a point to check in on a thursday or early friday if possible, as there are minimal vehicles near the roadway. I have stayed in 636 and 1030 most recently and did ok. The loops are fine to drive around, but backing into some of the spots can be a pain. 636 was the last spot on the loop and required me to actually pull across the main street to back it in. Just use a spotter when backing, especially for the front of the truck as there are numerous stop signs, trash cans, and short poles w
