Well, I'm trying something new. I replaced the wald hangers with pipe hose clamps (4 on each side). They are snugged down over duct-taped wrap sections of the rack. I think they bear the weight with less jiggling around so they won't grind down on the rack. And I used to zip tie the rack to the side legs and I'm not doing that now - they may rub when loaded down with beer but with the zip ties (which prevent rattling when folded) they rubbed for sure. I also cut some tarp pieces and then duck-taped those to the areas that had rubbed. If this doesn't work, then he can buy a second hitch and sometimes borrow my Burley Travoy I'm getting in November. ($100 new, with 20% members coupon at REI and $100 gift card for signing up for REI Mastercard-great deal!). His rack and baskets work great for everything else he carries.
