I just got off the phone with Ed from US Cargo Contol (E Track Straps & Tie Downs for Trailers: Ratchet Straps & E Track Tie Downs
). He's a very pleasant and knowledgeable fellow, and we spent some time discussing best practices. I sent him to a photo of a gutted bus so he could see the structure. I anticipate buying from him when the time comes. He can be reached at 855-206-6269.
Note: they sell 2', 5', 8', and 10' lengths, but he suggested staying with the 8' and under because they have to send the 10' by freight. It's that sort of concern and advice that impressed me. And the price, while not free, is certainly reasonable - considering the forces involved and my lack of engineering degree, this seems like a good move.
