I have been full-timing in a 42’ Class A for about 6 months. This CG has the largest sites I’ve come across yet. In most, you can barely get your awning out without hitting the neighbors rig. Here, I’m guesstimating 30’ to the next rig, on either side. I am in lot 11 and next to me is a picnic table (not too close) and beside it, my space includes room to park my toad. And I could easily get two cars in that space. And THEN, the next site.
Clean, nice laundry facility, and a restaurant right at the front of the park! Three bars of Verizon.

Per the GPS coordinates, I found the turn off for this location off Byway 12. I wish I would have snapped a pic but didn’t think about it till I was long gone. The entry was no-way a road. Maybe it once was, but not anymore. Not only was it a lumpy, bumpy mess, but Weeds have grown up both sides and the middle. I backed out and left. Wasn’t comfortable driving my Jeep there, and no way would I venture it in my rig. I did have 2 bars of Verizon service at the entry point. Not sure if that would stay the same had I gone to an actual campsite.

I have a 42’ motorhome towing a Jeep and found plenty of spots able to accommodate my needs. Plenty of shade, but there are also wide open spots available. Occasional ATV’s but I never found them to be a nuisance. I stayed the full 2 weeks.
You can dump your trash at a rest area just 3 miles towards Bryce Canyon. You can also dump and fill your tanks for $10 at the Red Canyon RV park 6 miles the other direction.
