Just speaking for ourselves, we definitely don't think Aqua Hot, washer/dryer or dishwasher are critical for full-timing.
We did without them for 16 years with our 40' Newmar motorhome - Spartan/Cummins.
Dishes for two are minimal. Why do you need continuous hot water except if you have a washer then you'll be doing constant laundry because of their size. We went to a laundramat every two weeks and finished in 1-1/2 hours. It's no big deal.
Public parks were always our first choice - national, state, national forests, COE, county and city. We also loved boondocking on a lovely stream or lake. Therefore, we could never have a washer or dishwasher.
Everyone is different and it just depends on YOUR WAY of RVing. Full-timers don't need full hookups.
