I noticed in the back of the catalog where they show the "gear", you can buy tunnel reinforcements for the Pro-RMK. Any thoughts from anyone who's seen these and the way they attach? I am one of many who suffer from extremely bent D8 rails. B Bars are just a tad too late for me now. Just wondering if it will be necessary and if so how much they will cost. I would rather be pro active (no pun) this go around and save the headache.
