  • How do wheel well boxes mount?

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

  • What goes inside 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 smooth installation and maintenance. Electrical equipment may be mounted inside the wheel well box or the wheel well panels behind the box. We recommend cutting ventilation for electrical equipment, heaters, or pumps.
