You guys really should downsize to a truck camper, less maintenance & no plates. Lighter weight & better gas milage. But then again you still need to stop every two to three hours for a potty break.
Been there, done that. Tents, vans, slide-ins and trampolines. I'll take a Class A or Class C RV over a truck camper any day. Hot shower, heat, galley, head, queen size bed, all for not much more cost in gas mileage. I get 10 MPG...uphill, downhill, pulling the boat, doesn't matter. Most pickups/SUV's only get 12-15 MPG when towing. In the big scheme of things I'll go with comfort in my old age and sacrifice a few MPG's. The only drawback is robbing the ATM to fill it up. You only live once.
