Actually, you should have posted the Making B1700 logging-road proof? here, since Modification is not about what you're planning to do, but what you've already done. That's why the subtitle is:
You show us yours...we'll show you ours! . So, I'm going to move it here and lock this down. We don't want to get two topics going about the same thing. It confuses people and search as well.
BTW: the subtitle for Problem Solving is
Share your problems, concerns, fixes of Molded Fiberglass Trailers
Thanks for the understanding!
