Depending on where you are...
if you don't have heat in it, you should leave it winterized...
How about bringing bottled water for drinking and
using the campground showers until you move in ?
in lieu of that though,
You have a res fridge or rv fridge ?
do just the reverse of winterizing, drain and blow out the lines, then run water to flush...
for the icemaker - with an rv fridge you can get to the back and drain the icemaker, otherwise, just let it make ice until it's not pink
