How many of you simply don't bother with hookups?

We have a toy hauler with 120 gal fresh, 60 grey and 40 black. We run the generator to keep our batteries up over 12 volts and watch TV every night. We take a Navy shower every night. We can go a week or 10 days without hookups. When we need to get re supplied with groceries, we get hook ups for the night. We love USFS and to boon dock! Works with us and the savings go in the furl tank!
