I bought the HD years ago for my silverado, that was the reason why I bought this brand again, but the HD was better built, better fit, looked like it was built with better quality materials, this one looks very fragile, leaks by the tailgate, the last piece of the cover needs to de 1.5 to 2" longer that way the new seal can actually work better, the latched are very hard to operate sometimes they get stuck inside, sometimes you have to close them for the cover to latch.

The cover needs to be 1.75" longer for a 2018 GMC SLT Z71 Crew Cab Short Bed to fit properly at the front and rear. The foam has to be installed as far back as possible on the front bulkhead to get the seal on rear to rest 5/8" on tailgate. This should be about an inch back more on the tailgate to get the support member closer to the tailgate.

Great Looks

Really like the sleek design and low profile. Installation was a breeze following the utube video. Design is really about an 1" to short. Consequently, the cover barely touches the front of the bed and tailgate. All that being as it is, this is MUCH better than a competitors that was on the truck previously. It's a keeper for a few thousand in tools.

Simple and sleek

The installation was a simple process after reading the directions and watching a YouTube video it became a no brainer.

I have had the Bak MX4 on my 2018 GMC Sierra Denali for almost two weeks now and love it. during installation the hardest part was getting it centered and even on both sides, but once that was done I tightened it down and have not had any issues with it moving out of place. This past week with it on we have been getting a ton of rain and it barely leaks, only where the tailgate meets the bedside (not Bak's Fault more of GMC's). Great protection and water resistance!

I purchased the MX4 for my 2015 Silverado. The youtube video is the way to go. Installed by myself in less than an hour. It is not water tight as some can get in but overall it stays very dry. I would definitely purchase again.

Nice

This is a very nice unit. It looks good and the installation was easy and straightforward. It would have been even better if the 21% coupon in effect at the time of purchase was applicable to it.

Many features, super convenient and good looking too.Easy to install as well.Any minor leak issues could easily be remedied with just a little silicone.A good value with the added security of protecting your cargo.Superior customer service: literature, contact numbers for any problems.Lastly, I love the ability to open / close the tailgate with the cover locked.
