Not mentioned yet is Flying J, when I get gas I check air pressure and get water and propane if needed. Another thing to think about is battery power and waste tank sizes. Two GC batteries and 60 gals of FW are good for 7 days of dry camping with showers everyday. After a week laundry has to be done bedding changed etc. Batteries are at 50% SOC and need to be fully charged so we stop at a FHU CG with electric and a laundrymat, dump fill and ready to go again. Most NFS CG's also have water and with a senior pass are half price. Rest areas are harder to find that still have dump and fill but are still there if your google sanidumps. In over 100,000 miles and and 17 years of travel I have always been able to find water somewhere when needed. How big are your waste tanks? That may be your limiting factor.
