When i was first considering a roof raise, I'd thought of doing this. It would be much like a Class "C" RV. But if you do this, make sure the overhang does not obstruct your view of stop lights. Especially those in smaller towns that are hung close to the intersection on the driver's side. We've several of those here in my neighborhood and when stopping, everyone has to lean forward and crane their neck to look up at the stupid light to see when it changes.
