Leroy (the OP),
What kind of RV do you have?
Perhaps you could trade straight across for another type of RV? You mentioned a tow dolly, so I assume you have a motorhome(?). I know I don't want to RV in anything large or tow anything ... too much get-ready, park, setup, tear-down, unhook at home, etc., hassles for us.
We RV in a small Class C and don't tow. The rig is just about ready to go anytime. We keep it in the backyard plugged in to keep the batteries up. This kind of setup makes it almost trivial to take on short or long trips on short notice. I'm really glad this type RV is what we have at our ages - 67 and 70.
