My 110 feed is underground and probably buried 75+ years ago, & is on a 15A breaker, which is why I can't do anything easy. BGE wants way too much to do a new feed just to the garage, so I am thinking generator for the few times I need to draw extra power. Too cold to do anything for awhile, just trying to plan for spring. No real heat in the garage either. The 7,000# would work fine as long as I can get the narrow track on safely. They quote a 35 1/2" opening and the car has 36" between inside tires.
