I've rented U-Haul trailers multiple times to tow behind my 2021 Model Y with an integrated hitch receiver. It is a pain in the butt to hook the safety chains to the openings on either side of the receiver. Today I bought a couple of stainless steel heavy duty anchor shackles at Home Depot and added a little Loctite thread locker to keep the shackles from coming loose. I expect they'll be MUCH easier to reach when hooking up the chains.
