It was easy to assemble and it looks great. I had the exact one on my other truck. Its not 100% water proof. It keeps most things dry. It definitely keeps taking people from easily stealing stuff from the back.

Platinum cover

Awesome cover. Very easy to install. Love it.

Michael Goutis
Easy to install

Installed it by myself with no help. Was very easy. I do recommend two people in lifting the actual cover. It’s not terribly heavy but is a little awkward due to the size. It’s definitely possible to do by yourself with no problem or issues. After I ordered it; it took exactly a week to arrive on my doorstep. The quality of the Bakflip MX4 is worth the price. was cheaper than everywhere I looked. I checked locally and online. The only thing I didn’t do with my cover was install the drains because my bed has a factory spray in bed liner and I didn’t want to drill through it. Other than that I highly recommend this cover. The Bakflip MX4 has the best warranty for the type and price you pay.

Smooth as butter

It’s been something I’ve been wanting to get for my for awhile. I purchased it but wasn’t sure if I would be able to install it. Boy was I wrong. It went in like warm butter. I did have help lifting it, but installed it in an hour.
