Winter Storage Questions

Great first season in our 2008 Winnebago Destination/DP. Alas, winter will be coming to soon here to Maine. Due to other obligations, its time to put the toys of summer away now.

Winterizing the fifth wheel was easy. Drain the lines, put the pink in the lines, drive to winter storage location, remove battery and return in the spring.

Class As are a wee bit more complex. The research that I have done is primarily focused on draining the lines and putting the pink in the lines. I get that.

(I have located indoor winter storage for a reasonable rate. This opens the driveway up for safe snowblowing, et al.)

What about the diesel fuel in the tank? Leave alone or add the winter additive? Fill the tank or ????

The batteries are another concern. All the research says to charge them up monthly. Which assumes that there will be unfettered access. Unfortunately, that will not be the case. The batteries will be fully charged when the rig is put into storage.

What I'm thinking is to disconnect the house batteries from the coach. Setting the battery Aux Batt Switch to off. And return in the spring with a battery charger and good book to read while getting the charge back up to operational.

For those of you who do long term storage over the winter. What have you done? What have you learned? What are the dos and don'ts?

Tnx in Advance.
