wick, i just looked at the l.s. pic's of your rig---- um--- , a rectangular out let under your bay just in front of the tandem you would have to put a NASCAR, heavens forbid, long length wise-- short height wise out let. you would have to have it custom made, -- isn't everything-- because you would be going from round back inside the basement to rectangular under the bay. but yes, i think it'd work great not to mention soooooo coooool.--- guess you know by now i ain't right. 2" by 10"-- 1 1/2" by 12", seems to me some of the old passenger buses grey hounds etc were that way--- just a thought-- mase
