Video Transcript for DeeZee Trailer Cargo Organizers - Toolbox - DZ77 Review

Today were going to review part number DZ77. This is the DeeZee Specialty Series Underbody Toolbox. This is silver in color. This underbody box is ideal for storage under your flatbed truck, your dump truck or your trailer body. Its made of a rust proof bright tread aluminum construction. It is rectangular in design and again, is an underbody style.

It has the single dropdown door. As you can see it drops down from top to bottom and it has the chains on each side that prevent the lid from totally falling down. This will provide easy access to the cargo inside your toolbox. Here you can see the stainless steel locking T handle latch. You just turn it and push the handle out of the way.

That would keep the lid closed. It can be locked. It does have the two keys here that should just turn it, turn the keys and lock half way. The handle will still open, but it will not turn to release the lid. To open it just turn it the other way half a turn, that will allow you to twist it and open your lid.

You notice right here it actually has a water tight C channel that goes all the way around. On the very front here is a foam bulb seal which will prevent water from entering your box and damaging anything on the inside. This is a very simple installation. This mounts to the underbody of your vehicle and it is required to use the DeeZee Universal Mounting Kit that is sold separately. It is part number DZDD-2502.

Its basically two L-shape brackets that will mount on each end and allows you to bolt it up underneath the body of your vehicle. This part is made in the USA. A few overall dimensions on this, the overall length of this toolbox is 36 inches. The width is going to be 20 inches. The actual height is about 18 inches. The interior capacity is 7 cu ft of space on the inside. This does come with a limited lifetime warranty. Again, just to show you, you close the lid, twist the handle about a quarter of a turn, push it down it keeps the lid in place. To lock it, just turn this lock half a turn. It even has a nice little cover that will cover the lock itself to prevent any dirt or grime from getting inside the lock. That should do it for the review on part number DZ77 the DeeZee Specialty Series Underbody Toolbox.

Review from a similar Specialty Series in Underbody Tool Box


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??

Fit perfect, easy mounting hardware.

Review from a similar Specialty Series in Underbody Tool Box


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.

Review from a similar Specialty Series in Underbody Tool Box


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.

One year later the boxes are still holding up great. I’m happy with them.

The box is good quality and it fits on my atv. It has a dust and rain gasket on the lid but, it doesnt have any latches to keep the lid closed. I guess I missed that in the description because it doesn't say there are latches, it just says its lockable. If it had a latch it would get 5 stars.
Doing bisiness with etrailer is easy and totally convenient


Comments
This utility chest only closes full with using padlocks such as part # 37DAT
Master Lock Shrouded Padlock
$16.46
. I checked and we do have a larger chest, part # DZ8537B
DeeZee Red Label Truck Bed Tool Box - Utility Chest Style - Aluminum - 6.4 Cu Ft - Black
$416.65
which is 37.13 inches long x 19 inches wide and 16.62 inches tall. It comes with a locking handle as well as two keys.

The box us acceptable for the price. It serves propose for occasional travel. Probably not the weight and quality of components for constant use, but perfect for travel trailer.

Review from a similar Specialty Series in Underbody Tool Box


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.

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...


Comments
Be sure to consider that adding heavy items generatorbatteries,etc. adds to the tongue weight and towing towing capacity limits.

Review from a similar Specialty Series in Underbody Tool Box


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.

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.

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.

Review from a similar Specialty Series in Underbody Tool Box


Great deal. Purchased at "dinged" version of the product so paid about $87 vs. $290 for undamaged product. Dinged version was noted as "everything works", and it does. About 10-15 mins of gentle banging and twisting it looks as good as new, after a little bit of use. Nothing stays new forever. Winch and battery fit inside on the bottom nicely, will install a a pull out shelf/tray above the winch/battery for storing tie down straps and bolted a solar trickle charger on the lid to keep battery charged. A nice piece and a cost effective find for me. Thanks.

    The DeeZee Specialty Series Underbody Toolbox - Steel - 6.75 Cu Ft - Black, DZDB-2601, is a very strong box. This box is very heavy weighing about 95 lbs. It will definitely keep your expensive equipment secure, but it won't be very easy to move without handles like you mentioned. Another option for you would be a black aluminum option like you mentioned. For that, I recommend the DeeZee Red Label Truck Bed Toolbox - Utility Chest Style - Aluminum - 6.4 Cu Ft - Black, # DZ8537B. This...

    DeeZee brand running boards are made in the USA but the Westin kit you mentioned is not. So for your 2021 Jeep Wrangler you'd want any of the steps at the attached link. Probably the most similar steps would be the part # DZ77HR.
