The heavy-duty steel construction was immediately apparent, inspiring confidence in its ability to handle heavy loads. Compared to some cheaper, universal shanks I’d seen, this one felt like it was built to last, a testament to the Equal-i-zer brand’s reputation.
Initially, I was excited to get my camping trailer level and tested on the road. It’s surprising how much a simple shank can improve the whole towing experience.
