i was very brief
we left from quitman stayed over night in vernon on 287 just north of wichita falls, local mom and pop place called rocking A rv park, very nice. they even escort you to the site and make sure your all good, then on the other side of dumas and stayed the night in dalhart,

then limon, then cheyenne, then up to gillette over to devils tower area
iirc...385/287 in CO was dry, dusty and not to bad of a road surface, and one rr track in the middle of now where and BAM there was a fast train.
the little bit in OK was horrible like driving on a rail road tracks thump thump thump. lots of little towns with places to pull off and stretch the legs
in limon we stayed at a KOA...it was the really the only thing there...two closed hotels and a KOA...it was weird
we stayed in lamar on return trip
fuel prices in wyo dropped 30 cents a gallon as i remember
Cheyenne has some awesome museums and the UP rail road depot
corral rv park in dalhart was superbly clean and easy to get settled
i also did the route to ensure i could go around denver and avoid the traffic
