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.

2022 Chevrolet Silverado 3500

etrailer gets 5 stars. Site was helpful, shipping was ahead of schedule. No issues there. All the issues are with the product. Unexpected of a weathertech product. Material is flimsy, I have GM premium all weather floor liners and the storage box can’t maintain its base because the edges slip on the floor liners. The floor liners also have a lip on them that I had to cut a notch for on each end to try and prevent the storage box base from flaring out. I’m sure the box holds its form fine on carpet, I’d be interested to see how it sits on weathertech brand floor liners. It holds all your stuff secure. I wish it had been more rigid in design and didn’t have all the wasted space because of the way it was engineered. Not worth the price even on sale!!!

I spoke to my contact at WeatherTech about this and he said while those are OEM liners, they are dealer installed instead of factory installed. Since that is technically an aftermarket liner, we cannot guarantee the fit with the storage box.

by: is very thin plastic, bulges and spreads out when items place inside. Would be perfect if made of heavier material. Dont know know that I would buy again.


I love the concept, but weather tech could have done a better job of designing it. There is a lot of waisted space in the way they designed it. As for ordering-shipping, everything went off with out a hitch

Chevrolet Silverado

Great fit, just what my Silverado 2500 needed

Works great! One of the best things I’ve bought for my truck

the weather tech under seat truck storage box has a lot of room and keeps my rear seat free of clutter, also it was perfect fit thank to leslie c my sale person. thank you


I really like it. Exact fit.


Wouldn't order this again. Had one on my 2011, was thicker, and bolted down. This one is flimsy plastic, with a small strap to hold it in place. Had to buy a black ratchet strap to hold it back while plowing. Keeps sliding forward. Not worth the money.

by: was a great transaction! I was surprised at how flimsy the outside walls of the storage box are so that is why I gave a 4 out of 5.. Otherwise great box!


Good product. Super service. Ordered Sunday and received Wednesday. Great


Very satisfied.


Your storage box fits well, but I was surprised that the material was thinner than I expected. I replaced a GMC storage box I had laying around from an earlier model vehicle. Yours fits better, but is not nearly a rugged as the GMC model.

2020 Chevrolet Silverado 3500

This is a nice size under seat storage box, fit well and easy to install, it can be easily removed for cleaning.


Definitely needed this as all my stuff was falling out from under my back seat. Seems to fit relatively well but it could be a little bit longer.


Your service was great and on time. Most of the time I don’t receive my product as indicated by the seller. Yours was on time as you said you would be. Thank you.


It is great


Best to keep things from rolling around. Great for extra tools.


fits like it should
