Thanks. The scissor truss doesn't quite do it but the Skandia design might. I haven't seen that one before. I'll get to a truss co. this winter and see what they can do.
ps I went to the Garage Store last weekend. You can spend alot of money on lifts, flooring, cabinets,etc. I was drooling in their display garages.
Some of their epoxy flooring paint systems are over $5/sq ft!
