My previous truck, a 2008 Duramax, came from the previous owner with a powertrax/retrax. Loved it for it's ease of use, remote open and close, but it had been on his prior truck which was a 2003ish duramax. It was worn out. I finally scrapped it but while it worked I loved it. I'd consider getting another. But I'm still deciding on if I want to get a topper or not.
