There are a few sites which will accommodate a 40’ RV. On the Recreation.gov website, check the “allowable equipment” section. Your towed vehicle is another issue. I suggest calling the North Kaibab Ranger District office to see if there’s an adjacent location (maybe alongside the entrance road?) where you can park the trailer/vehicle. I can tell you that Demotte is a fairly tight campground, as in not a lot of space to maneuver. It’s also very beautiful in the fall!

Most of the sites had tents and only small trailers when I was there last. A forty foot RV might be pushing it.

We fit into space 2. Our total length is 53 feet. That’s the best I can do. 2 is a first come first served site.
