Not bad for the money.
For the money I spent, I feel it is a decent cover. I knew it wasn't the top of the line. It fits fairly well and looks good on my truck. The only real problem I have is the fit at the tailgate. The right side that has the latch fits snug. The left side however sticks up and doesn't seal. If both sides were latched, I'm sure it would be a better fit. The only way I can see to make it better is to bend the lip on my side panel, may or may not do that.
I replaced a Roll 'n Lock cover that had been damaged by hail (broken vinyl covering). I selected the TCUSA Tonneau because it has powder coated slats and no vinyl, which should be A-OK for this hail-prone area. I was, however, reluctant to give it 5 stars overall since my bed was wet after a recent rainstorm. I gave it the benefit of the doubt that the water in the truck bed might have been condensation and not necessarily a leak. So far, so good!
