Installed just in time for rain
I love the look and appreciated the ease of installation. It took me about an hour to install and it was very timely since it rained the next day. Don’t have to worry about protecting my tools anymore.

Previously owned a Ford F150 that I installed the BAK MX4 and loved it. Had for about 4 years with no issues. Traded vehicle for this Dodge and immediately purchased a cover for it. The instructions are ok, but the online install video makes installation a breeze.

I had the same cover on my Silverado so I knew exactly what I wanted on this truck. Have never had a problem, and compared to other covers it's more versatile and easily operated.
