I was wondering if anyone uses the factory receiver hitch that has been BEEFED up. what does everyone else use? I want to try my luck this summer on a sled and was told by a guy that ownes a sled and pulls himself that 26 inch height is the best and that receivers work but flex too much and can tear off. What is the best set up out there?Does anyone have pictures?Does the sled operator supply the loop for the hook. I have never seen how they hook up.
