We've not had any freezing weather since February in
Mississippi, which the Travato survived admirably (although I have no idea how - we were newbies back then and had NO clue what we were doing!).
We have every intention of staying ahead of the cold weather as we drive south down the Atlantic seaboard, but I'm sure it'll catch up with us sooner or later. It's certainly not that warm where we are now!
I'd have to read the manuals again to fully winterize, but there are three easy-access drains under the slide door that empty different parts of the water system. They allow you to empty the pipes without emptying the tanks as well. We used them once up in northern Minnesota - useful when you think it might drop a bit below freezing but not enough to freeze the tanks.
The biggest problem is the fan heater: it's either on or off and the van isn't very well insulated. Consequently you get big undulations in temperature. Not ideal, but we just wrap up warm and wait for the sun to come back out :)
