I figured I'd bring my poly wheel well to them so they can copy it. My issue is I'd like the wheel well to be independent of the decking. As it is now, the well flange goes under the floor making it impossible to get out. If I just put it on top of the decking, the plywood edge would be exposed. Not good. That's why I thought maybe a heavier gauge steel could be fabricated and welded directly to the frame and be done with it. Galvanized sounds good too, RM66caravel
, but it will still have to mate with the frame under the decking. If you think that it's strong enough to probably never have to deal with then I think it's probably a more economical option.
