WeatherTech Underseat Storage # WT56HR Fit a 2018 Toyota Tundra with Crew Max Cab?

Expert Reply:

While we do have a cargo solution for you, I confirmed with WeaterTech that the Under Seat Truck Storage Box - Black # WT56HR does not fit your Crew Max cab on your 2018 Toyota Tundra. This is because it only designed to fit Double Cab styles. Also, we do not carry any other under-seat storage boxes from other brands that are confirmed to fit your truck.

With that being said, a great alternative option is a rooftop bag like the Rightline Range 2 Rooftop Cargo Bag - Water Resistant - 15 cu ft # RL100R20. Not only is the Range 2 an economical option to carry cargo, you do not need a crossbar system to mount the Range 2 to the top of your bare-roof Tundra. To secure to your vehicle, you simply attach the clips/clamps to the door frames.

I went ahead and attached a demo video that highlights the features of the Range 2. Since this vehicle has raised rails, the installation for your bare roof will be a bit different.
