As I said, I'm borderline disabled - depends on the day. Here in NYC, there is more than one Generac dealer (and found out a friend is one of them! I thought he was only in the fire alarm business, but nope).

I won't need/use a tank, I'll live with piped in NG

Well see what the total estimate comes out to. Looking at the bigger transfer switches Generac sells, it'll cover the whole house, so...
