For people who have stayed in their RVís over winter would adding tank heaters also be a wise precaution or unnecessary? In my mind if the tanks are freezing the pipes have likely frozen too? Thanks in advance!
If you are well skirted (no drafts) AND block all the holes in your frame (I used gorilla tape) to help stop drafts, AND you put a couple small ceramic heaters underneath on the lowest setting, you should be fine without tank heaters.
Again to monitor your temperatures buy a package of 3 remote thermometers. Put one outside, one underneath and one in the underbelly via the access hole under your kitchen island where the drain goes down.
