Good Fit, easy install.

Very pleased with the BAKFlip MX4. Have only had it installed for a week, but it works well and provides good solid coverage.

Easy install

The bakmx4 was very easy to install, put the rails on,center cover and 2 bolts in front to hold it down and that's it.it does have drain hoses which will hopefully keep bed dry.there is a lot of exposed rubber on the exterior which looks okay but I hope it holds up to sun exposure
