Hey Mooseman. Wishing you a Merry Christmas!You could make your own Rock Tamer type flaps. I made some for the Sierra when I'm towing our RV. At the height of your Voy, you could use just one truck flap cut in half.
I'm not really doing any rock crawling. Just some sand washes where there are occasionally some small rocks....the size of a basketball or less, and they still catch. I'm going to try using some rubber washers under them to let them "give" a little. If that doesn't help, I'll keep them off and only install when I'm towing my small trailer. Or I might buy a cheap rubber/vinyl type of floormat and cut it up and make my own flaps.Ya I finally got the proper flaps for my LT trailblazer but i know they will catch on rocks but i dont really fock crawl, mostly just overlanding stuff.
They are easy enough to take off and then put back on for a weekend.
