Terryallen,
Are you suggesting that folks who can afford an RV are poor? I believe the opposite may be true.
Any campground equipped with 50 amp pedestals can do level 2 charging. I'm never in a "mad dash" to get south, though I do admit to driving longer than usual to get below the snow line.
How often have you driven your RV (or car) 1600 miles in one day? My personal best is a little less than 900 miles--and that was driving at 50 mph. I did stop for a nice nap about 1/2 way, which would have been an opportunity to rapid charge an EV. I did stop to make meals as well. That's three more charging opportunities without "extra" waiting.
My first class C was a diesel and the hose to the fuel tanks foamed like crazy. If I really wanted to "fill to the gills" it took about 30 minutes. I'd fill until the pump clicked off, and then go wash the headlights, continue to fill and then wash the passenger's side window, and etc.
My "normal" driving is about 3 to 5 hours per day.
