I seem to be the odd man out here. I winterize, put 3 desiccant containers inside, seal it up and remove the negative cable off all batteries. I also inflate the tires to max pressure to minimize flat-spotting. It sits 6 months straight without being started (beginning of Nov. to end of Apr.).
In the spring, I reconnect the batteries and she starts right up without issue.
In recent years I have indoor storage, however with my previous RV, I did the same - only outdoors. Only difference is I did a thorough check of the Dicor on all the roof seams in the fall.
