We stayed up top Carr for two nights. The camp sites are huge. There is actually one site with a dump station surprisingly. It was on the wrong side of our camper though so we didnt use it. Most of the sites are backed up to a wash, so during monsoons this could be pretty crazy. It was windy both nights, and Im guessing its windy quite a bit up there. We have an 11' camper, and I doubt you could pull anything larger up Carr Road. Way too many switchbacks, and very steep at times. My camper only weighs 2,500 lbs being towed with a new F-150 and I was slipping at times. There were quite a few tent campers both nights.
