I know it would be alot higher then you'd be willing to go(and for good 
reason), but ever notice the height that the high mileage(be it gas or 
electric) vehicles are built at. They don't allow pressure build up 
underneath by keeping the body high and the exit area larger then the 
entrance area(bottom side tear shape). I know total body reconstruction is 
not a feasible option for you KT, but thought I'd throw this out there for 
thoughts on it.
