I am storing our PUP in one half of our 2 car attached garage. It is insulated and stays around 40 degrees +/- throughout winter(wisconsin). This is our first winter with the new PUP and want to make sure if I should do anything more than I have already. I drained all the water lines that were used including hot water heater, shower/toilet cassett, inside sink, water hookup, and outdoor shower. I used a shop vac to blow all of the lines out. I did not use the fresh water tank at all during our excursion. I didn't add any antifreeze knowing it will be in the garage all winter long. The garage doors never stay open longer than it takes to back in or out. Any tips are appreciated. Suppose to be dry this weekend and in the 30s so if I need to do anything extra, that will be easy for me to do. Thanks!
