Ok posted on here before about when I picked up new 2970RL they didn’t have the eq4 hitch I wanted. Have always used the chains and friction sway control ones on smaller lighter trailers. Did my research and decided on the eq4 for a number of reasons. Now since I brought the trailer home before the hitch came in, I had to install it. The dealer set up the head before I got there with the measurements they took off my truck originally. No problem, the instructions are pretty clear for setting up brackets etc. Only problem I had was getting the sway brackets in the head to move to attach the bars. I finally got them to move and lubed them but my question would be for those that use this system, I would guess that they would become easier to move after some use? The videos all showed these moving pretty easy.
