I was visualizing Brian's idea of raising a bus and going off road and I saw that the first time you drove off the road on to unlevel surface the bus would tip over and roll to the bottom of whatever incline you were on. And I thought that it might be a good idea just to go ahead and roll it first. Then replace all the broken glass with thick Plexi and you would have a pre-rolled bus and you wouldn't have to worry about damaging it any more, since it will roll over every time you took it off-road. I guess that you could keep it from rolling if you hung something VERY heavy from the bottom like a piano or a refrigerator. Anybody ever try this?
