After 5,000 miles of driving with the DiamondBack HD truck bed cover on my 2020 Jeep Gladiator Rubicon, I can confidently say that this cover lives up to its reputation. When it comes to securing gear, protecting against the elements, and offering unmatched durability, this is easily one of the best investments I’ve made for my truck.Â
But before I give any product my stamp of approval, I like to put it through its paces in real-world conditions. That’s exactly what I’ve done with the DiamondBack HD, testing it through sand, snow, rain, and everyday use to see if it truly delivers on its promises.
Choosing a truck bed cover isn’t a decision to take lightly. Some covers provide excellent weather protection but limit access. Others offer security but lack the strength to haul heavy loads. With the DiamondBack HD, you get the best of both worlds—a cover that can handle 1,600 lbs. on top, features secure deadbolt-style locks, and is built from .100-inch 3003 alloy aluminum for maximum durability. The custom-fit design means it installs seamlessly on your specific truck, and the weather-sealed perimeter keeps dust, moisture, and debris out of the bed.
In this DiamondBack HD Truck Bed Cover review, I’ll dive into its specs, features, build quality, and real-world performance, helping you determine if it’s the right upgrade for your truck.

So, as you can see from these specs, DiamondBack comes to the yard ready to play. They aren’t messing around with sub-par materials or lazy designs. This truck bed cover is well put together, to say the least! Speaking of which, let’s shift gears and discuss the build quality of this thing.
DiamondBack Build Quality
It goes without saying that the truck cover is built like a tank. The aluminum alloy cover is both lightweight, yet strong, which is the ideal combination for having a long-lasting, durable bed cover but without bogging your rig down with a ton of weight. The stainless steel hardware is definitely a bonus, as it resists rust and corrosion for years and years of reliable service.
The locking mechanisms are worth noting as well – there’s two locking mechanisms and with the deadbolt rods that secure under the bed rails, you get the ultimate in security. And with trucks like my Jeep, when I lock the doors, the tailgate also locks, so this bed cover certainly gives me the security I need for my gear. 
No matter where you look – underneath at the support structure, on top at the finish, at the hardware, locking mechanisms, and cleats, this cover is beautifully made and shows an extreme attention to detail.
DiamondBack truck covers are able to accordion, so you can access the truck bed from the front or the back. Since I carry my Pelican hard shell case and Trek Remedy 9.9 bike on top of the cover, I can’t take advantage of the accordion feature. I don’t need it to accordion, but it’s worth mentioning for those of you that might need that added level of access.
It’s worth noting that you can order these covers for your specific vehicle, so they fit your rig perfectly. Because the cover is so well made to the particular specifications of your rig, installation is a breeze. In fact, it only took me about two hours to install the cover, and that includes taking several breaks to play with my son.
All told, it was closer to one-and-a-half hours of install time. The well-written and easy-to-follow installation instructions allow for a quick install as well. Even the shipping materials DiamondBack uses were well put together. The cover came in a large crate that protected the cover from any damage, which isn’t always the case when you order something online.
DiamondBack HD Truck Bed Cover Performance
One of the most impressive things about the build quality of this truck cover is its weather sealing. DiamondBack clearly took its time in developing this system. The thick neoprene compression gasket that lines the perimeter of the cover (shown below) does a superb job of keeping sand, rain, and snow out of my truck bed. 
Even at Glamis Sand Dunes – where there’s obviously a lot of sand (and wind) – the DiamondBack HD did its thing and kept all that dirt out of the bed of the truck. And just a few weeks ago up at Big Bear, the cover worked like a charm to keep a TON of snow and moisture from getting into the bed. 
Even when I’m washing the truck, this cover keeps out the high-pressure stream from the wash hose. Everything inside has remained completely dry. I’ve been highly impressed thus far! One of the handiest features of this cover is the system of cleats around the perimeter.
You can easily tie down your gear to secure it whether you’re headed out for an off-road adventure or making a quick trip home from the home improvement store. I’ve even used the cleats to secure one end of my hammock when only one tree was available. 
In terms of carrying weight, I haven’t tested out its 1,600 lb. capacity – I simply have no need. However, I often hop on top of it to set up my tripod for shooting photos and videos, and I feel completely secure standing on it. I opted for the Smooth Black version of the DiamondBack HD, mostly because I liked how it is reminiscent of a bed liner.
It looks absolutely killer, though I think the Rugged Black and Aluminum options also look great. As an aside, I was a little worried about the ease of cleaning the Smooth Black cover. It has a bit of a gritty texture to it, so my concern was that hard, caked-on mud would be hard to get off. I was wrong. This cover cleans up quickly and easily without any fuss.

Why This Bed Cover and Not Something Else?
You might be wondering why I went with this particular bed cover… Well, the answer is that I did a ton of research, read a lot of reviews, and did my due diligence.
Through that process, I found DiamondBack HD, and they simply impressed the hell out of me. Seriously – just read the reviews of this cover and you’ll see that I’m not the only one singing its praises! Part of my research was thinking about what I needed for my type of adventuring.
I could have gotten a bed topper, but that would have meant that my bike and Pelican box would have to ride way up on top – where they aren’t nearly as easy to access. (Speaking of which, I carry my bike and Pelican case on a Front Runner rack system that is made exclusively for these truck covers. I’ll have a review of the rack system coming up in the next few weeks.) 
I also could have gone for a bed rack, but that would have left the bed of the truck exposed, so I wouldn’t be able to carry any gear in there, unless, of course, it was something that could get wet, muddy, or potentially be stolen. So, getting a bed cover was a logical option for me. It allows me to have my bike and Pelican case easily accessible while also allowing me to use the truck bed as a weather-sealed, secure area for storing my gear. It’s the best of both worlds. 
DiamondBack truck covers are more expensive than a typical bed cover. However, this is not a typical bed cover – it is much, much better. The old adage that “you get what you pay for” definitely applies here. The higher upfront cost will be well worth it over the years and years of service that this cover will provide. I have no doubt that it will give me the utmost of reliability and durability right up to the point that I decide to sell my Jeep. And you can bet that I will install a DiamondBack HD bed cover on whatever truck I get next!
FAQs
How secure is the DiamondBack HD Truck Bed Cover?
The DiamondBack HD is one of the most secure truck bed covers available. It features 3/8-inch deadbolt-style rods that latch under the truck’s bed rails, making it nearly impossible to pry open. The side-facing key cylinders add another layer of security, and if your truck’s tailgate locks, it further reinforces the overall protection. This makes it an excellent choice for keeping gear, tools, and valuables safe from theft.
Is the DiamondBack HD cover truly weatherproof?
Yes, the DiamondBack HD is designed to handle extreme weather conditions. Its EPDM compression gasket seals tightly against the bed rails, preventing water, snow, and dust from getting into the truck bed. Even in harsh conditions like heavy rain, snowstorms, and dusty off-road environments, this cover keeps your cargo completely dry and clean.
How much weight can the DiamondBack HD support?
One of its standout features is its ability to support up to 1,600 lbs. of evenly distributed weight. Whether you’re hauling ATVs, motorcycles, or extra gear on top, the seven structural support studs ensure that the cover remains stable and secure under heavy loads.
How difficult is it to install the DiamondBack HD Truck Bed Cover?
Installation is straightforward and takes about 1.5 to 2 hours. The cover is custom-built for each truck model, ensuring a perfect fit. It arrives well-packaged, with easy-to-follow instructions, and no drilling is required. If you’re comfortable with basic tools, you can install it yourself without professional help.
Can I still access my truck bed with the cover installed?
Yes, the DiamondBack HD features front and rear panel access, allowing you to open either end of the cover for convenient loading and unloading. If you need full access, the panels can also be completely removed. However, if you plan to mount gear like a bike rack or rooftop cargo on top, keep in mind that it will limit how easily the panels can open.
