SOLUTION:
So it was incredibly frustrating to get here but Retrax can and will ship you the Pro locking mechanism for free if you have this issue…and if you intelligently bitch enough. The Pro latches on both sides, the One is only on the drivers side.
First off, Retrax is 100% aware this is a problem but can’t really explain how or why it only happens to some units/vehicles. Maybe it’s because I jump my truck? But I digress. What was frustrating is that the initial person I was dealing with in customer service basically said I’m shit out of luck. Their solution was allowing me to pay the difference to upgrade to the Pro which I refuse to pay for because I don’t need or want the aluminum version.
I had to escalate to a guy named Jeremy who finally offered to send me the Pro locking mechanism for free. My argument was basically, “so you know this is an issue, and your way of fixing it is making me pay you more money to upsell me a product I don’t need?” What’s really annoying is that they market the difference between the One and Pro as polycarbonate vs aluminum. They mention in a buried FAQ that the pro locks on both sides, but don’t say anywhere that the One doesn’t or that you might have this issue. So yea, the locks are a big difference between the two as well as the material.
Also annoying that one of the people made me adjust the rails to be out of tolerance. They only allow you to be +/- 1/16” out of square from cab (no adjustment) to tailgate. They told me if I adjust the rails in to squeeze the cover tightly at the tailgate that this would fix the problem. Doing so puts them 1/4” out of square. It did not fix the problem. Had to go through this exercise to prove to them it wouldn’t fix it.
