Storing Roadtrek For Winter

[Storing Roadtrek For Winter]

I am getting ready to store my Roadtrek for our Wisconsin winters.

Three questions:

1) Is it best to remove the two twelve volt coach batteries and keep them in my basement where I can charge them periodically and keep them from freezing?

2) Is it best to fill the vehicle gas tank and add Stabil to treat the gasoline for a six month storage?

3) Should I disconnect the vehicle battery to prevent running it down during storage?

Thanks,

Jerry

[6 Volt Batteries For My Roadtrek]

I just purchased a used roadtrek and need to replace the weak batteries. They are two 6 volt batteries in series. Any thoughts on what I should be looking for in replacing them. Stay with 6 volt or go to 12 volt? Capacity of battery?

Should I charge the batteries before installing them into the Roadtrek or just let the inverter/charger do it? I didn't know if my charger was adequate to do the proper job.

Also is there a recommendation on what voltage level where the batteries should be charged without relying on the crude battery indicator in the Roadtrek?

[Dometic RM 2554 Refrigerator Won't Propery Cool On Propane]

My refrigerator works great on 120 volt but will only maintain about 50 degrees on propane. The flame is blue and I just got back from having it serviced and cleaned but it is no different. They said they cleaned the burner?? I checked the temperature in the freezer and it appears to be OK, but not the refrigerator. Any thoughts what to try next?
