Is it possible to install a house ac, one dedicated to the trailer that would run on 220 vac and only 220 v for the ac. This trailer, a 37 foot North Country, one ac in LR, none in BDRM. This unit is a long term stay trailer. The only time this unit will ever move again is during the next earthquake. We are in Ramona ca. where we have already seen 116 in early June. If I have to install an ac in the bdrm I would have to increase the shore power from 30 to 50 amps anyway. Why not run it as 220vac for a more efficient unit. Any residential hvac trailers out there who could give their two cents worth. Thanks all, ya'll have a great site here. Jim Bob
