When to winterize

[RooDude09]

I have a Rickwood 2607 ultralite. Here in my area of California it's been getting down into the high 20s at night. I was wondering if it would be necessary to winterize. The trailer is covered and the underbelly is "sealed" meaning I don't see any tanks underneath. Never had any problems with any of our other trailers but maybe I'm pushing my luck. Thanks for any input.

If it were me I'd be at least draining the lines and pouring some af in the drains, and probably draining water heater. But that's just me.

As long as it's the high twenties and not low twenties with warm temps of a day it should not be a issue. If the days are cold as well I would winterise.

If there is water in your water heater and water in the lines and water in the toilet and traps, you are definately pushing your luck in the 20's.

What do you mean by, "covered?" Is it inside a building?
