      • How do wheel well boxes mount?

      The wheel well boxes are designed to shoot into the wall and the sub-floor. We recommend using rivet nuts inserts for the wall but self-tapping screws will work for most builds.  

      • What goes inside of the wheel well boxes?

      The wheel well boxes are designed to house all water tanks, plumbing, and electrical. Easy access hinged doors allow you to get in and out for a smooth installation and maintenance. Electrical equipment may be mounted to the inside of the wheel well box or to the wheel well panels behind the box. We would recommend cutting ventilation for electrical equipment, heaters, or pumps.

      • How is the bed removable?

      The bed is designed in two identical sections that are removable via two handle cutouts on each. The beds are primarily mounted on top of the wheel well boxes for a minimal open-garage style bed but can be taken out to accommodate tall items for transport.

      • How do I apply paint, stain, or sealer?

      - Lightly scuff the entire surface of the cabinet that you plan on coating with 120-180 grit sandpaper.
      - Apply 2-3 coats of primer prior to applying your main coat.
      - Always apply a finish when you're happy with the paint to get a long lasting appearance.

      - Sand the surface on all faces with sandpaper traveling with the grain of the wood.
      - Apply stain very cautiously to a section of the cabinet that will not be visible to gage the volume and pressure you need to achieve the look you want.
      - Apply stain evenly with a rag, sponge, or spray gun until all surfaces are coated.
      - Please note that overlapping surfaces may make the stain darker on the overlapped areas.
      - Always apply a finish when you're happy with the stain to get a long lasting appearance.

        Wheel well cabinets and Bed

        Really nice quality !! Had a couple issues to deal with but Dimitry took care of everything.
        I’d say the mark of a good business isn’t when things are perfect but how they handle issues that invariably occur.
        I can’t say enough good things about how I was treated by Dimitry and his crew the cabinets are well built and nice looking.
