I'm with you. I start back from Mexico April 1, but drag my feet to get back to Minnesota until April 21.
I do however shut everything down and drain all the water out of the heater about twice a year. I used to do it less often, but after letting the water run through a strainer after 2 years of not emptying it, and getting a cup or more of gag, I now do it twice a year.
And generally, I leave the campground with grey and black tanks empty, fresh water full. You never know when you might have to sit a while.
