For Dinosaur Nat'l Monument we stayed at Green River c.g. in the park with our 40' motorhome. It was very nice and it had some long sites. As I recall some of the pull-thrus have a curve and a big rig would have to back into it from one end. You couldn't pull thru.
They do accept reservations. We were there in Sept. and plenty of open sites.
Dinosaur Nat'l Monument CampgroundsFlaming Gorge was just a few days stop as we weren't going to fish there. We stayed at Firefighter's campground in the park. Dry camping. Again, in Sept. there were plenty of open sites. It's a pretty campground right on 191 overlooking the lake.
