Niner,
I'm on gen power only, at this point. I possibly have a few options next winter... 1) solar floating, 2) maybe storing the bank at my brothers place and grid floating, or 3) possibly renting an outdoor storage/parking spot, with hydro, for about $200/month.
Actually, option 3 would be a viable one, provided I was allowed to stay in the camper while parked in the storage lot. $200/month would be cheap winter living. (A room rental is anywhere from $400-600/month, for shared accommodations). I worked out my hydro usage, and even with running some electric heat in certain areas, like the fridge cabinet, I would use about the same amount of hydro as someone who had their work truck, or whatever, plugged into a 600w block heater for 8 hours a night. (about $25/month). So that's something I'm going to look into for next winter.
