Great videos
I went to the North Rim of the Grand Canyon in 2002. but way to the west to Toweep. Was tent camping and got a spot right on the rim. I could have tossed a rock from my tent and the next thing it would have hit was 2500+ feet down. No guard rails.
When i built my trailer in 2007 I built it with the road in there in mind. 60 miles of gravel, washboards, dirt and ruts. Just a few weeks ago I found the NP pamphlets of that spot and they did say "Trailers not recommended" Didn't say, Not allowed
I might get to make the trip again soon with the trailer, I have drug it over many miles of bad road, would like to add shocks to it but that would be the only thing before such a trip. But might not even do that. Check the wheel bearings, pick up another set and pack some grease. check nuts and bolts. And a few spare tires and I would not be to worried to go.
A few years ago National Geographic published a book called "The One hundred must see places" or something like that. The cover photo was taken about 50 yards from where I pitched my tent. Yes, it is a fantastic place.
