This is a regular sight in my neighborhood when people return home late from their trips and just want to go to bed. They first run cords from the house to trailer or MH's parked at the curb.
Not only is it easier on the food in the refer's, it's easier on the batteries that start losing capacity after they run dead.
Doesn't need to be a full 30 amp (or larger) hookup, a simple 15 amp wall outlet will keep the batteries charged.
