Protect the interior of your trunk or cargo area with this weatherproof, impact-resistant liner. Advanced surfacing helps trap fluid and debris; textured surface holds mat securely in place; and custom design ensures a perfect fit for your vehicle.


Features:

  • Custom molding allows for complete coverage of your trunk or cargo area
  • Advanced surfacing provides channels to trap fluids and debris for easy cleanup
  • Raised side lip keeps spills contained
  • Unique material is formulated for durability
  • Textured surface securely grips the floor and holds your cargo in place during transit
  • Black finish complements most interiors
  • Made in the USA


Your vehicle not only gets you from point "A" to point "B"; it also allows you to transport people and pets or to haul luggage, lumber, outdoor gear, groceries, plants and more. And all this activity deposits dirt and grime, damaging your interior. Protect it with a WeatherTech Cargo Liner. Digitally designed to fit every contour of your trunk area, this custom liner is constructed of TPO - a weatherproof, impact-resistant material made to last. The cargo mat features a textured finish that helps to prevent items from shifting during travel. And the raised lip and channels provide barriers to stop liquids from spilling onto the carpet, making it easier to clean up messes.

I love the fit and durability of the WeatherTech Cargo liner. It came rolled up, but after unrolling and setting two coolers overnight on top of it to straighten, it lies flat in the back of my Pilot perfectly.



by:

The fit is lacking quite a bit (like 3-5 inches off in places) also wish I didn’t get the one that covers the whole floor in one piece. I wish it was 3 pieces that snap together for easier cleaning because this design you end up dumping all the crud on the floor of the truck while trying to take the mat out to clean it.



by:

Weather Tech floormats for our Ford escape are great and fit perfect.Thank you etrailer for selling me some GREAT products



by:

Does not fit the 2018 Hymer Aktiv class B motorhome on Promaster chassis. See pictures. notches for seat posts are not even close. The floormat extends into passenger side lower step well causing trip/foot snag when entering vehicle. Does not extend into area between seats leading to another raised area prone to trip/foot snag. Not good for RV use. I gave it two stars for quality of material. I'll be requesting return/refund.



by:

The mat is exact size needed! One mat is waaay better than the individual ones that came with the Sprinter!
Very pleased with Etrailer service!!



by:

These mats are fantastic, they fit perfectly, keep the floors and carpet clean and protect the factory flooring. Excellent mats and great deal from etrailer!



by:

This was the longest hitch ball mount I could find anywhere. I used it with a short extension for my 2021 T G so that I could open the back doors without hitting the trailer wheel crank. With my new trailer, Intact Flyer Discover, I don't need the extension and can still open the doors. Works well.

Cargo mat delivered did not completely
Fit
the cargo area. I'm assuming the wrong mat was sent. 2018 Chevy Equinox LS . Waiting for response back from eTrailer. I called 800 # on July 11, 2017 three times from 4:30pm to 5pm EST and computer prompt for service with product was #3. On hold twice for over 15 minutes with no explanation or human contact. Called third time and used prompt 1 for sales thinking they would surely pick this call up. Same 15 minutes on hold without any contact. Hung up again after unnecessary wait.
Hopefully this will get worked out and at the minimum a credit should be offered for the screw up and non existent customer phone service.



by:

Received the mats 6 days after ordering using the "free shipping "option. I feel this is reasonable and the tracking provided was accurate and up to date.

Now about the mats. I have owned many vehicles and have always tried to protect the interior and keep it as new looking as possible. I believe these mats will help me do that. In s word, they are great. They fit really well and the color match is spot on. The texture is non-slip and they are flexible enough that taking them in and out is a very easy. In short they are perfect for my vehicle and I would most certainly buy them again.

I will definitely use "etrailer" again for any products I need that they carry.

They're WeatherTech--their name and quality speak for themselves. I have these in all my vehicles.

My order was lost by UPS. I was notified by etrailer of the loss and I was assured that they would resend my order. Received it today, Thank You.

Great floor mats



by:

Fit perfectly to my Ford E450 ( RV Forest Sunseeker 2018). Thank you very much, great job! Fast delivery to Canada.



by:

I started looking for these floor mats by going to the WeatherTech website. I put in all the truck info and was surprised and disappointed to see that no mats came up. Then I did a google search and they came right up on etrailer.com. I was a bit skeptical that they weren't available from the manufacturer, but I could get them here. I received them today and they are the real deal. The price was competitive and they were delivered in two days! Great job etrailer!



by:

Fits perfectly. This is my 4th set of Weathertech floor mats and all have proven to be great!



by:

The product fit, at a gamble for me, ordering for a 2023 version of a 2022 product. I've previously been helped and appreciative of eTrailer for their stellar service and excellent video instruction.
Quick shipping, competitive price, they got what you need.......I'm pleased. What more is there to ask, these days?



by:

WeatherTech stands true to their claims of custom fit. My floor mats dropped in place with no effort. So much nicer looking than the plastic flooring in the cab of my motorhome. Clean up will be easier now that the mats are in place.



by:

They are the best, saves a lot of damage to the floor and cleaning



by:

Awesome - fits great, awesome etrailer customer service.Keeps the truck neater and cleaner. Comes out easy for hosing off.



by:

Fitment is not great. I would choose another brand for my next purchase. I had an issue that Weathertech said they would not correct. However etrailer corrected the issue themselves. I would definitely buy from etrailer again but never anything made by Weathertech.



by:

The floormats were a perfect fit for my Roadtrek RV. I received them within 4 days of placing the order. Great follow up by customer service.



by:

Fits perfectly, came really quick, and the price was good
all things you want in an on-line order.



by:

At first I thought that they were thin and pretty cheap, then I installed them. Wow! Absolutely perfect fit. Could not ask for better.

  • 2015 Honda Pilot Cargo Mat Liner Recommendation
    The Weather Tech Cargo Mat part # WT40378 that you referenced will fit all the way up to the back of your second rows of seats when the third row of seats is folded down. Your best option would be to run the # WT40378 when you have the third row of seats folded down and then go with the part # WT11AVMCB for when you have the third row folded up.

  • WeatherTech Cargo Liner for 2015 Honda Pilot
    WeatherTech's Black Cargo Area Mat # WT40378, as well as the tan # WT41378 and grey # WT42378 versions, is intended to fill the space between the backs of the 2nd row seats and the far rear of the vehicle interior. This covers fits if the 3rd row seats are folded down.

  • Will Husky Liner WeatherBeater Stay Put and Keep Groceries from Moving in a 2011 Honda Pilot
    So far we haven't received complaints of the Husky Liners WeatherBeater # HL24361 allowing bags of groceries to slide around but then again this isn't really guaranteed to keep stuff immobile. It will definitely be better than the current surface in the back of your 2011 Honda Pilot but it isn't really "sticky". This liner will be too rigid to roll up if you are needing to use a 3rd row of seating in your Pilot but we do have the WeatherTech # WT40378 which is flexible enough for you to...

  • Will Floor Mats from a 2007 Honda Pilot Fit a 2009 Honda Pilot
    The first generation Honda Pilot was from 2003-2008 and the second generation Honda Pilot was from 2009-2015. Since a 2007 Honda Pilot is a different generation than a 2009 Honda Pilot the floor mats will be different. For a 2007 Honda Pilot I recommend using part # WT440591 for the front, part # WT440222 for the rear, and part # WT40182 for the cargo area. For a 2009 Honda Pilot I recommend using part # WT441741 for the front, part # WT441742 for the rear, and part # WT40378 for the cargo...

  • Cargo Liner Function With 3rd Row Seat On 2010 Honda Pilot
    For the 3rd row use in your 2010 Honda Pilot, I reached out to my contact at Husky Liners and the WeatherBeater Custom Cargo Liner # HL24361 is too rigid for use with the 3rd row, the cargo liner would need to be removed. I also reached out to WeatherTech and the WeatherTech Cargo Liner - Black # WT40378 will allow you to roll it up when you use the 3rd row seat and it comes shipped rolled up in this way, however, they don't recommend you keep it rolled up for long periods of time (2-3...
