DIY Installation:

Installation Difficulty: difficult | 3 people
Installation Time: 1-2 days
Tools Needed: Power Drill, Rivet Nut Tool, Screw Driver, Drill Bits, electrical equipment

  • 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.

  • What does the warranty cover?

This unit is backed by Serg Supply and Valley Hi Vans for up to 3-years on Craftsmanship. This warranty does not cover any damages to the unit due to tampering with or modifying the components. 

  • If you plan on staining:
  • 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.
