LOL IN FACT this evening "while raining" I was digging around for "stuff" and remembered ALL THE BODY MOUNT TO FRAME hardware off the "several" Dakaotas/ Durango's I junked. These are beefy huge washers/ rubber absorbers, with HUGE center bolts. If they won't hold it, I don't know what. And yeh.....part of the reason for the box is to hold junk in LOL
I have "a bunch" of keyed alike locks, and will likely add some big hasps to lock the thing shut
