Video Transcript for WeatherTech Under Seat Truck Storage Box Review

Jake: Hey guys, it's Jake here with etrailer. Today we're going to be taking a look at . I'm going to show you some of the cool features on the Weathertech under eat truck storage box.This under seat storage box is going to give you a place to properly organization your tools, so they're not just sitting on your seat or on the floor board of the back of your truck. Now, what's cool about this is the box is only going to utilize the space underneath the seat that would be otherwise wasted space. You can see it fits underneath our seat very nicely and it's out of the way when our seat is down.The box is going to have a durable and sturdy plastic construction to be able to resist against any liquids you may have if you're storing any types of oil or anything. It's going to be resistant to those and easy to clean up.

As you notice, both on the driver and passenger side, you're going to have these deeper hole pockets so that you can store tools such as our ratchet traps there and not worry about making contact with the seat. And in the middle here, it's going to be a shallower compartments for wrenches or screwdrivers or anything that's lower profile.One of the most convenient uses for this storage box in my opinion, is going to be for your ball mount. If you're putting your ball mount in the bed of your truck, we all know that they're going to bounce around in the back when you start and stop. But if you set it down inside your case, because of that plastic construction, it's going to hold it so that it's not rolling around in your backseat.Now that we've gone over some of those features, let's go ahead and show you how we got it in place. It's going to be very easy to set into place.

It's all going to be one piece. Just set it down in your back seat. And we do have an included strap that will go through this slot and tie down to the tie down point here on our spare tire tools. What we'll need to do to be able to get our buckle through that slot, we'll need to take the strap out, slide it through our slot, and before you put the buckle back on, it's a good idea to slide it back behind that bracket and then replace your buckle. Then you'll cinch it down.

Get it nice and tight so your box can't move forward on you.Now we can go ahead and replace all of our tools in our organizer so that they're all nice and tidy. And with all our tools in place, we can go ahead and lower our seats and see that they're not going to make any contact. Well, guys, with all that being said, that's going to do it for a look and installation of the Weathertech under seat truck storage box.

WeatherTech Under Seat Truck Storage Box - Black - WT4S002

Average Customer Rating:  4.6 out of 5 stars   (116 Customer Reviews)

Keep your truck clean and organized with this under seat storage box. Custom made to fit your vehicle. Large capacity is perfect for storing jumper cables, tools, and all sorts of supplies.

2014 Chevrolet Silverado 1500

Perfect fit in my truck. The only thing that keeps it from getting a fifth star is the fact that the hole for the strap does not line up with anything under the truck's seat. I had to attach it to the seat belt support, which is several inches away from the strap hole.

I recommend taking a look at our video on a 2017 Chevy Silverado 2500 at mark 2:02 to see how we handled using the strap.
