Like you we live in the snow belt, Michigan. Peronally I wouldn't dive ours over the salted road to move it for vacation. I just got done this year painting all the rust on the structural steel from the lousy Fleetwood paint job.
Not too mentioned the thought of trying to beat the snow on the roads traveling. Rather jump on a jet and head somewhere warm.
But ours is in a nearby storage yard. Until we got a power sight I went every two weels to run the gen to keep a charge on the batteries. I don't remove them. This year I'll do the same even though we now have electric at the storage site. Put a load on the gen and run it.
