I live in the Sacramento valley where the winters are mild. I never winterized my old TT. Now with my newer class a, we hope to use it in the winter. I was curious if other folks in the Sacramento area winterized their RVs.
I live on the other side of the valley from you and only drain my low water points and drain my hot water heater for ten season's so far. I've had lows in the lower 20's for a 4 or 5 hour period. I don't think it being a Class A would be any different then any other RV.
Many years in San Jose and still lots of time in the Bay Area and Sac. I've never known how to winterize :h because I never needed to. :h Bought the current rig out of Seattle and had to flush out the lines forever. ๐
Brisbane and Sac this Jan and no plans to winterize. :B

Does the temperature go below freezing for more than five days and nights, if only on a few nights you are OK, if your old TT was OK then your new A has better insulation.
