Just talked to a lift retailer. Asymmetric 2 post is 135" wide. Needs 4" of concrete. Reinforce concrete with mesh instead of rebar. Needs 12 foot walls but might go 13 ft anyway.

Really, the delay was because I was initially given incorrect info from the town office on setback. They said 20 feet from rear property line. Can't do that and make anything look right.
New investigation shows about 5 feet from rear property line. I can live with that. Full steam ahead. With planning.
