Stop Replacing Underbody Boxes That Fail Prematurely

Stop Replacing Underbody Boxes That Fail Prematurely

The fleet managers who come to Tank Vault have already wasted money on underbody boxes that rust through or leak at the seams. The RC Industries M Series eliminates that cycle with .125 inch aluminum construction — noticeably thicker than the thin-gauge boxes sold at big-box stores. The automotive bulb seal creates a weatherproof barrier that keeps moisture out, and stainless steel L-style hinges will not corrode even in road-salt conditions. This is a vetted product built to last through years of daily fleet use, not a disposable box you replace every season.

Configurable Storage for Any Fleet Setup

Configurable Storage for Any Fleet Setup

With sixteen available sizes ranging from 24x14x16 up to 96x24x24, the M Series adapts to flatbeds, service bodies, and trailers without modification guesswork. You select the exact dimensions that fit your mounting space, then choose between diamond plate aluminum, smooth aluminum, or configurations with stainless steel doors. The optional welded-in or adjustable shelf lets you organize tools by size instead of piling everything into one compartment. Tank Vault curated this range because one-size-fits-all storage forces compromises that cost fleet managers real productivity on job sites.

Drop-Down Access That Works in the Field

Drop-Down Access That Works in the Field

The pan-formed drop-down door with integrated gutter sheds water away from the opening, so you access your tools without reaching into a puddle. Heavy-duty door retainer chains hold the door at a stable angle — no sudden drops or hinge strain when you are working on uneven ground. The stainless steel L-style hinge provides smooth operation that does not bind or squeak after months of exposure. For crews that open and close underbody boxes multiple times per day, this precision in the hardware makes a measurable difference in workflow speed and technician frustration.

Compatibility Check

Confirm your vehicle meets these requirements before ordering.

  • Minimum 14" to 24" of clearance between frame rails or mounting surface
  • Flatbed, service body, or trailer with accessible underbody mounting points
  • Sufficient ground clearance to accommodate selected box height (14" to 24")

Built for Real Work

Engineered for professionals who mount storage where it matters.

“Mounted two of these on our service trucks six months ago. The .125 inch aluminum is noticeably stiffer than the boxes we were replacing, and the bulb seal has kept everything dry through rain and pressure washing. Crew likes the drop-down door — no more reaching over a side rail to grab what they need. Solid purchase for a fleet that is hard on equipment.”
