I’ll add my 1 1/2 cents to those who are wisely recommending either more time or less distance on your coast to coast trip.
We left Charlotte to Yellowstone to Seattle to San Fransico to Vegas back to Chatlotte. We didnt dilly daddle but didn’t rush either. We were gone 5 weeks and we didn’t take the RV either. Towing at lower speeds, having to camp outside of Seattle or San Fran. setting up/tearing down every day or so - all of that would of added a minimum of an additional week and a whole lot more scheduling stress to the itenary. Like others have said, unless you plan on driving ungodly hours every day, this woll not be an enjoyable trip for you or anyone else in your party.
