winterization tips?

Reaching out to our cold weather friends who have to store their motorhomes for the winter...a couple of questions:
i) to cover or not to cover? (the full covers seem daunting but the roof-only seem practical?)
ii) remove the chassis/engine battery or start it up every couple of weeks?
iii) hydraulic jacks down and coach levelled, yes or no?

i) we don't cover. I prefer to just clean and wax the exterior. This helps when we take it out for PM work during the winter and when I take it out for drives. I do cover the tires.
ii) We do not remove the batteries. I disconnect the power and use the battery disconnects (both engine and chassis). Once a month I reconnect and run the engine and generator. Every other month I take it for a drive.
iii) Hydraulic jacks retracted - not down, not leveled. I sit the tires on hard plastic pads, rather than asphalt.

After talking with several of my camping friends here in northern Pa Pocono,s. I,ve decided this yr. to go out and buy a full cover for the class A motor-home, just to protect the top mostly of snow, and ice. As for the battery I will use a battery tender all winter, with ocassion,s of starting it up along with the gen. The cover will give me a peace of mind while sleeping through some of these nasty storms we get. As for winterizing I use about 6 gal of rv anti freeze, and people laugh at me for using so much, I just say hey its ony 3 bucks a gal and I will always have a peace of mind while sleeping, and not worrying about fixing pipes in the spring.

At one time I used to cover our MH during the winter. It got to be a real pain getting the cover on our 38' class A. Then we built a large shop with a carport big enough to park the MH under it. We have the MH winterized at a local RV repair shop. I know it is easy to do the winterizing, but with their program, if they de-winterize it and there is a problem, they repair it on their dime. As for the batteries, they get cleaned and the fluid topped off. I then install battery tender on them and leave them in place during winter storage. I check the fluid level once a month just to ensure they do not go dry. Being that the MH is parked on a gravel pad, I put down pieces of 1" plywood for the tires to be on. The propane tank is topped off and the diesel is topped off with #1 fuel. We do leave dried food item in containers and cloths in the MH. This is in case there is any reason that we need to move into it during the winter. This may be over kill, but one never knows here in Alaska.

No cover - A cover can do a lot of damage when the wind blows and the cover starts flopping around

Battery needs to be fully charged before removing or disconnecting. I installed disconnects on all the batteries to completely disconnect them ( you could just remove one of the terminals). Removing the battery and storing inside would be better, but I'm lazy. The battery must be fully charged or it will freeze.

I don't have jacks, but I believe it would be better to leave the jacks retracted.

I leave batteries in and leave the coach plugged into 120v all winter.

With the air bags inflated, I build four towers (one for each jack/leveler) with 2-inch thick planks (pressure treated) so they are just touching the jack base. I then deflate the air bags so everything settles on those towers, thus relieving some of the weight on the tires.

The tires have 2x12 pressure treated planks under them.

I blow the lines out with air (including the ice maker), remove the water filter, drain the FW tank and fill the traps with anti-freeze.

Camp Freightliner folks suggested that if it sits for more than a few months, that I run the engine at a high idle (to build enough heat for the def system to work) once a month. This is done with the tach at 1700rpm and using the cruise control. I would prefer to drive it once a month, but I also have a full cover on it, so it sits.

I run the generator for an hour 2x per month.

It's worked for me.
