Winterizing for Tucson?

[TimandMarilyn]

Hi, we are planning on storing our RV in Tucson November-February. Then we will head there mid February and stay in it until April when we will bring it back to Colorado. Does anyone have advice on whether we need to winterize during this time frame?

I can't imagine you'd need to do any winterizing.

I leave smal amount of water with 1/4 cup of cooking oil in the waste holding tanks to keep seals from drying out, toilet full of water with plastic wrap covering the bowl, all stoppers plugging sink/shower drains so P traps don't dry out, open low point drains, leave 5 gallon bucket 2/3 full water for moisture & scatter a couple bags of Ramik Green (found at Tractor Supply) pest deterrent pellets under/around on the ground. Freezing will NOT be problem, lack of humidity & critters are.
We are about 45 miles towards Casa Grande, the weather last year was unseasonably warm, I actually wore short britches for most of the season.

I doubt winterization would be a problem. Here in W TX I usually drain the FW tank and blow out the lines. Put antifreeze in the traps and toilet bowl as well as the waste tanks. Now that we winter in FL we don't worry about it.
