You forgot the most important rule of all: Never ever get under your bus without chocks and blocking the body in case of an airbag deflating. Too many people have been killed this way!!!
now airbag, that would be a serious topic and this is not the place for serious lessons.
besides Eagles don't have airbags, we have the expensive, quality, porpoise-like, smooooth-riding rubber band suspension. no worries about any air deflation, unless my co-pilot gets that ice pick out near the tires.
