sounds OK, not so sure how it would be positioned though. if it had a wooden bed and canopy frame it wouldn't work, the wood just couldn't support the weight of vehicles and the like. I have seen a tank used like a bridge in an old WWII movie in the pacific theatre, but then again they were using Shermans to represent Jap "armor" in that film.
neat Idea though, inspiration for something else like that. thnx for sharing it.
