Letting it set for a week to a month:
o Charge batts with converter/charger for a few days, then unplug
o Turn off house power
--If leaving house power on:
o Turn off water heater
o Turn off pump
o Turn off refrigerator & open the door(s) to let it air
o Open windows & roof vents if stored out of the weather (as I do in the barn/shop)
o Empty black, gray
I don't mess with fresh while it is setting for up to a month, as I dump & refresh just before the next trip.
Winter: All of the above, and:
o Drain/flush water lines
o Pour in pink, draw until it comes out faucets/toilet/shower
Don't forget the stub line for the city water hose!
o Run a little pink down the drains to protect P-traps & gate valves
o Run Generator monthly with load as mentioned
o Run chassis engine monthly, take the unit out for a 1/2 hour or so every 2nd or 3rd month.
o Watch for evidence of mice. I put mouse bait under the hood and in other areas.
No doubt I've missed a few by drawing on memory when it is 95 degrees out...
