This subject may become very important to many of us in future years. The one thing I would like to ask is, would a "safety inspection" by a state agency or some recognized inspection system suffice to show that the bus has been maintained to some degree? Thinks like air brake check, brake drum and pad thickness, tire tread depth, etc. I know commercial trucks get spot inspctions at some weigh stations. There must be some mechnism to could produce a report that the insurance companies would accept.
It would not matter if house systems were not up to "Kevin" standards, as long as "safety" related items were up to snuff.
