I leave my coach plugged into 50 amp service in a fully enclosed unit. It is 70 X 22.5' which provides me with room for a small shop setup. Door height is 14'.

Unlike our wealthy members in TN, my unit is not climate controlled so I pay the electric bill to run a couple of the A/C's in the summer. I usually set them at 78-80 and spend maybe $80/month on electric in the peak months. Not too bad, and all the stuff Jon talks about stays a reasonable temp inside the coach. Biggest problem with this setup is a power failure. Knock wood, none in 2 years.

I would ask any of the places you check about installing 50amp service. Nice to have the full power option should you need it upon return from a trip, etc.
