if you’re serious about a truck with a camper, I would recommend Buckhorn to Temple Mountain Road, and finding some cool places to camp not far from the wide graded road. There are some amazing slot canyons down near goblin Valley that are on my list to explore. A number of the roads I'm familiar with that you listed aren't really big camper friendly.
I did Fixit yesterday. I wouldn't want a truck and camper on that road. It's nothing like it was a decade ago, but similar to last year when
@mbryson and
@Tonkaman ran it with me. We got a 100 series Land Cruiser up it on 33's, but he was locked front and rear and did some 3wheeling.
Every time I've done Fuller bottom it's been passable, but I don't know if I'd want to take a truck with a camper through there either. I don't even know if a camper would fit through the underpasses on 70. It would definitely fit in Eagle Canyon, but that's some serious wheeling for a truck and camper to get out of there.
Coal wash is fine, tight and bumpy in areas, but fun. Pinstripes are likely on wide rigs through some areas.
I've never been to the Copper Globe area. That sounds fun. I'm 50% right now, but will know Wednesday for sure.
