I understand many keep their RV's at off site storage and manage fine.
However I would not like that arrangement.
I require the convenience of seeing my rig everyday.
I go out and tinker around whenever I want. I fix things, mod things at my convenience at any time.
I wash interior and exterior without making any plan to do so.
RV stays plugged in 24/7/365 allowing me to extend my camping season through December. For me, keeping RV at home is a must. I doubt I would own an RV if I had to use off site storage.
