What kind of mileage do you get when towing vs not towing? Do find there is enough room inside for all your gear?

Good room for the gear. All glider stuff fits in the back. I also have a low-profile roof rack, though I don't need the space for glider gear. It just keeps my luggage out of the back seat.

I haven't measured the mileage towing. On flatland maybe a couple MPG less than driving with no trailer. Climbing mountains, maybe a bit worse. It's 15-18 MPG with no trailer, mixed highway and city driving.
