Video Transcript for Review of UWS Truck Tool Box - Chest Tool Box - UWS01066

Hello, everybody, this is Jeff at Today we're gonna take a look at this UWS 58-inch-long 5th wheel series truck bed toolbox with a gloss black diamond tread finish to it. Now this 5th wheel truck toolbox is the perfect solution for keeping your items safe, secure, and accessible in the bed of your truck while towing a 5th wheel trailer. It is designed to mount inside your truck bed, so it leaves your truck bed rails free for other use. And if you notice this box is designed with a low profile to it, to provide adequate clearance for the movement of the 5th wheel trailer. This is an 5/8 of an inch, extra-thick one-piece aluminum box, it'll hold heavy tools and cargo.

It is an aluminum construction, has fully welded seams on it so they're guaranteed not to rust. And we mentioned the finish is a nice gloss black powder coat diamond tread finish to it. On the front of the box, you can see it has the stainless steel lock handles on both sides and that's for security and corrosion-resistant operation. Basically you can open the box by just lifting this handle, or if you're on that side, if you just lift that handle, you don't need to lift both of them. On the driver's side, you notice does have a lock with two keys on it.

So just to show you if you pull up on the handle, you can open the lid, and then when you go to close it, and then just like that, you can turn your key a quarter of a turn and that'll lock both handles so nobody can get into it. And then just put your key back in and unlock it, and then you can open it back up. If you notice the handles are widespread, makes it easy to reach from either side of the truck. Now I do wanna show you the inside and we are gonna zoom in for that. Let me just turn this and we'll open the box up.

Now with the box open, you'll be able to see the inside portion. And I wanted to show you there's a connecting rod that goes from this latch to that latch and that connecting rod allows you, as we mentioned, the convenient operation to open from either the driver's or the passenger side, but what it's nice about it is they put this nice enclosure here over that connecting rod and that's designed to help prevent bending or jamming of the lock system. So if you have something in your truck toolbox that could possibly slide and hit that connecting rod, you don't want that to happen to where it might bend it. So they have this protection here that will keep anything from damaging that connecting rod. Now it is a nice beveled lid, has a patented foam-filled lid that provides insulation, protection from the elements.

It is a structural foam lid, which will reinforce the shape and strength of the lid. And I also want to open it up and show you there's a foam seal on the inside right here, if you notice, around the whole edge right down here, all the way up and around. This foam seal will help to protect the contents that you keep in here from the elements. Right here, it has the gas cylinders, one on each end and those gas cylinders will help lift the lid and hold it in the open position. It does use a piano hinge and a piano hinge will run the full length of the box. And that helps give you extra support to the lid for opening and closing it. Last thing I wanna do is give you a few dimensions on this. We'll zoom back out and we're gonna measure. I'm gonna measure the overall dimensions and then we'll measure the inside dimensions. So I'm gonna get my tape measure. So overall dimensions, we're gonna go from outside to outside, and it's right at 58 inches for the length. The width of it, again, outside to outside, 18 inches. And the height, bottom to the top is right at 10 inches. Now, when you do close the lid, that will add about an inch to those measurements, the interior measurement, you just measure the inside of it, is gonna be right at 56 3/4 inches long with this 16 1/2 inches wide, total depth size inside is about 9 inches deep. So it does give you on the inside about six cubic feet of usable space. And again, just to close your lid. But that should do it for the review on this UWS 58-inch-long 5th wheel series truck bed toolbox with the gloss black diamond tread finish..

UWS Truck Bed Toolbox - 5th Wheel Series Chest - 6 cu ft - Gloss Black - UWS01066

Average Customer Rating:  5.0 out of 5 stars   (4 Customer Reviews)

58" Long x 11" tall x 18-3/4" deep; 6 cubic feet; fifth wheel box with foam filled lid and paddle lift handles. Aluminum construction and black powder coat finish provide excellent corrosion resistance.


The toolbox is just the right height for my 5th wheel towing. I installed fasteners in the front of the bed and rear next to the tail gate so I could move the box forward or back depending on what I was going to carry with the 5th wheel.
I am very satisfied with the box.


Review from a similar 5th Wheel Series Chest in Truck Tool Box

The toolbox was installed in a 2010 Dodge 1500 Quad cab with a 6' bed. The bed had a bedrug previously installed and after the tool box installation I installed red LED's under the bed rail with a on/off switch near the tailgate.

  • Tool Box That Could Fit at Rear of Truck Bed of 2016 Ford F-350
    While we don't have a tool box designed specifically with the application you mentioned in mind you can install a tool box at the rear of your truck bed like you are wanting to as long as the dimensions of the box match the available dimensions in that area. For example, the # UWS01066 that you mentioned measures 58" long x 18" wide x 10" deep.

  • How To Prevent the B&W Companion Handle From Hitting a Truck Bed Toolbox
    I do have a few options for you but there is not a short throw handle available for the B&W Companion 5th Wheel Trailer Hitch part # BWRVK3500-5W. That said, you can adjust the distance from the cab via switching the position of the socket post assuming it is not already in the position furthest away from the cab and or changing the position of the pivot arms if also not already in the in the position furthest away from the cab. I have attached a few photos of these adjustments for you. If...

    To install a 60 inch tool box like the DeeZee Red Label 5th Wheel Toolbox - Wide, Utility Chest Style - Aluminum - 14.9 Cu Ft - Black # DZ8560WB to a receiver hitch on the back of your Class B Winnebago Aspect you would need a carrier a little bigger than our largest 24 X 60 cargo carriers, but I do have a solution for you.

  • Should B&W Companion 5th Wheel Hitch be Cut to Install with Tool Box in 2019 GMC Sierra 2500
    To be blunt you should definitely not alter the installation in any way of the Turnoverball Install Rails # BWGNRK1016-5W or the B&W Companion # BWRVK3400-5W, or the Companion # BWRVK3770 if you have the OEM pucks in your 2019 GMC Sierra 2500 with a 6-1/2 foot bed. There may be one option for you since you mentioned 18 inches wide and that is the UWS Truck Bed Toolbox - 5th Wheel Series Chest # UWS01042 (Bright Aluminum) or # UWS01066 (Gloss Black).
