Extang Trifecta Folding Tonneau Cover Reviews


Just short of perfect.

Reviewed By William T (Burton, MI) Reviewed for a 2012 GMC Sierra —4/20/2016 8:23 PM

Really like Extang's Trifold series covers. Have a solid panel model and while I like the stronger panels, fit and ease of use it did let in heavy rain at the fold seams. Also felt the gasket material that sets on the bed rails could have been better. Really appreciate the light weight of the Trifecta canvas/vinyl model. Easy install and use. Felt the fit could have been a bit more generous and again rubber gaskets could be a bit thicker and a stronger, denser rubber. So far no leaks.
