Video Transcript for DeeZee Trailer Cargo Organizers - Toolbox - DZDB-2601 Review

Today we're going to be taking a look at the DZ Specialty Series Under Body Tool Box. This is going to be constructed from a corrosion proof 12 gauge steel construction. As you can see, it's a rectangular design, under body style. It's going to offer convenient under bed storage for your flat bed pickup, dump truck, or trailer, and it's going to feature a single drop down door that opens from top to bottom, which is going to provide easy access to whatever it is that you have inside the box. I do want to go ahead and open it, so it's got the nice T handle here. Turn it, and the door will drop. I do want to point out that it has a nice sealer that goes around the opening to keep out dirt and moisture.

You're going to have a stainless steel locking T handle latch, that deters theft. It does come with two keys that are keyed alike, so either key will work for that lock. With it open, you can see you don't have to support it. It's got these nice strong durable cables here, that keeps the door in the open position without over extending, and you've got a nice large opening. If we take a measurement of the opening, going from side to side first, that opening is going to measure about 31 and a quarter, to 31 and a half inches. Up and down, the opening is going to measure about 13 and a quarter.

So a nice large opening is going to give you access to easily get stuff in and out of the box. To lock it, all you have to do is shut the door, close the latch, push it down, and simply put a key in, and move it to the locked position. All you stuff is going to be secured inside the box. When it comes to your installation, pretty simple installation. It's designed to mount to your truck or trailer using a universal mounting kit, part number DZDB-2502. It's sold separately.

It's available here at But I also want to mention that you may be able to bolt the box directly to some cross members or framing, depending on your application. In that case, drilling will be required, and hardware is not included. That's kind of a customized installation. But that's going to be dependent on your application. Again, the unit is a 12 gauge steel construction.

It's going to feature a really nice black powder coated finish. It's going to last a long time. Really nice design to it. Gives the box a great look, and it's going to do a great job at resisting rusting corrosion. I also want to mention, and it's going to be hard to see, but down here, we're going to have two hinges. You're going to have a hinge on this side, and same point on the other side. On the edge of that hinge, there's going to be a grease zerk fitting. One right here, and one right here. That does allow for pretty easy maintenance. You're going to attack a grease gun to there, pump in the grease, and lubricate those hinges pretty easily. Again, it designed for flat bed trucks, dump trucks, and trailers. Taking a look at the overall dimensions, we'll go from side to side first. It's going to measure 36 inches. The depth, just measuring the main body, that's going to be about 18 to 18 and one-eight of an inch. If we extend it out to that door right here, if we include the door, we're looking at something closer to 19 and seven-eights, to 20 inches. Then the height, that's going to be right around 18 inches as well. That's going to offer 6.75 cubic feet of space, that's internal. Again, overall, nice durable construction, and it is designed for flat bed trucks, dump trucks, and trailers. That's going to do it for today's look at the DZ Specialty Series Under Body Tool Box.

36" Long x 18" wide x 18" tall. Underbody tool box; 12-gauge steel with black powder coat finish; locking T-handle latch; drop down door; underbed storage for flatbed trucks, dump trucks, and trailers.


I use this on my custom teardrop trailer and I really like this tongue box.
One year later, this is holding up well. The only thing is that the lock hinge started to show a little rust almost right away, but it hasn't progressed too much. It was a little disappointing though.
That said, I love that this has a padlock instead of having to use yet-another small key (I already have 3 just for my teardrop). It wasn't something I considered originally but figured out as soon as I put my combo lock on it.
I do really like this tongue box. It was the perfect addition to my teardrop build.


Boxes arrived in 3-4 days. I got used ones and was very happy I didn’t pay the full price. They work fine just a few dinges. I painted the inside white to see tools easier. The boxes are aluminum, seems very light duty. I wouldn’t step on top of it. When you close the top, the sides flex when pressure is put on the latch. I would have preferred a heavy steel, but needed a small box for the location and this was the only one I could find. For an ATV it might work ok. Overall pretty happy- I just installed so we’ll see how they hold up over time. Next time I would look for a heavy steel one. I paid for 2 used ones the price of one new... to me a new one would not be worth the price they are asking... just too light duty.


I luv this thing... I use the fuel tank all the time.. the large capacity is awesome.. the toolbox is fantastic for capacity n the ease to reach.. U will not find a better combo on market today!


The DeeZee tongue box has been an ok box for storing all my off-road gear for my RZR and trailer items. Haven't had any water leaks or problems. Latch and lock have worked correctly. I mounted it on the tongue of my Aluma utility trailer that I use to haul my RZR. Most of the gear I have stored in it is pretty light weight. This box seems to be lite weight constructed; not sure how it would do for heavy items. One year using it and it still works and looks good on my trailer. This review template would not upload my photos??


First, I like it a lot. There is lots of room inside, it meets my needs and I would buy it again because I think it is a very good value! Cons, Steel latch which means 3 months outside and it is already rusting. (I will eventually replace with a marine grade.) The unit is very strong on the outer sides, but not so much in the middle. I am 200 lbs and can stand on the outer sides of it, but I would not try to do so in the middle. (Note - Manufacturer does NOT recommend standing on it at all and I am not suggesting you do!) Depending on your specific trailer frame and what you intend to put in the tool box you may need to add some bottom support. You can see where I added a support bar in the front. If I was doing this mount over again, I would add a support or 2 in the middle because a couple of spare axle hubs and a bottle jack are causing it to sag significantly.


Just picked it up, everything looks good. Now it gets customized to fit in my Jeep Cherokee XJ,,,,,,,,,,,,, ty


It was just as represented. Took only a few minutes to install and looks great. Good quality.


i returned the brackets and fashioned my own since one size didn't fit all.

the aluminum cargo bays (one on each side) are a great addition- glad i got them they are very handy and always in use.

heres a beauty shot of our caravan, passenger side, featuring a 5ft. dee zee cargo bay


Tool boxes work great .they hold all my roofing equipment . Leaving the bed of truck for hauling supplies . An the cab of the truck for hauling the crew .thank you so much for these boxes .


Well made box. Mounting hardware is woefully in adequate
Packaging is minimal and caused a slight dent.


Phenomenal product, great fit for my job trailer and allows the crew to stand on it if it is necessary to reach the top of the trailer from the front.


Fits 2 group 31 batteries with room to spare. High quality box that looks and works great. The box does not come with battery hold downs, which I prefer because I could mount the batteries any way I wanted.


Utility box on my camper. This will be a great place to store power cord,water hoses and blocks and a lot easier to get too.


Seems like a solid lightweight box. The latch and locking mechanism are solid and the hinge is reinforced which is nice. I also like that the gas strut for the lid has a sleeve so if any gear shifts it won't interfere or damage the strut.


Product does excatly what I want it to do Houses my propane Tanks and Battery with room to spare. Hopfully they won't get stollen again...


Fit perfect, easy mounting hardware.


Nice box neatly welded and door sealed great and the brackets for this box fit perfect,thanks etrailer


great tool box. I actually had put in speakers. And mounted it to the rear end of my atv I will submit photos as well.


Save me a lot when I look for lowest price fuel.


Excellent product and etrailer is my ONLY go to shop for all my trailer/business needs !!


Trailer box installed


I bought a scratch and dent So I can’t give five star. It came as described with dents on the lid. But it still works fine.


Nice looking trailer box! Fast delivery too!


Wish I knew how to download and send a picture to show my unique application. Mine is mounted on the front of an enclosed trailer and has a battery box installed inside, with room still to carry other essentials. I also plumed in tubing and wiring for a light switch and bright light. The box looks great, fit perfect, works perfect, and I love it. Thank You ETRAILER for a great product.


Very very well built. Excellent fit and finish. I needed a trailer toolbox with these particular dimensions so I bought this underbody box, but I mounted it like a chest (door facing straight up) and it has met my needs perfectly. We don't get a lot of rain in NM so water getting into the chest through the recessed handle area isn't a concern with it mounted in this the trailer is stored inside most of the time.
