  • Will these cabinets perfectly fit my vehicle?

These cabinets are cut to match the curvature of the ceiling and walls. Promasters have a uniquely flat rear profile and top profile, unlike other models. Note: Promaster cabinets have a 1/8" cutting channel on the top corner of each sidewall that serves as a cutting guide in case one of the overhead beams prevents the cabinets from fitting against the wall—this cutting channel guides where to cut to notch your cabinets to bypass the protruding beam. 

It is strongly recommended that this cabinet is mounted using rivet nuts as specified by our Installation Guide.

  • What are the differences in material choice for upper cabinetry?

All upper cabinetry materials are made from the same paint-grade plywood used in custom kitchen builds and are designed to withstand years of daily use.

Prefinished Maple

  • Semigloss finish
  • It does not take stains or seals
  • It takes very well to paint
  • No finish work needed - already sealed and protected
  • Lightweight and durable

Unfinished Maple:

  • Lighter shade
  • Takes very well to lighter stains or whitewash stains
  • It takes very poorly to dark stains
  • Very easy to paint
  • You can take mineral oil/finishing oil for a nice light finish
  • Sealing is recommended but not required
  • Lightweight and durable

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


  • Lightly scuff the entire cabinet surface that you plan on coating with 120-180 grit sandpaper.
  • Apply 2-3 coats of primer before applying your main coat.
  • Always apply a finish when you're happy with the paint for 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 gauge the volume and pressure you need to achieve the look you want.
  • Apply the 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.

  • The Promaster only has one beam in the front for mounting.  What should I do?

    Our Promaster upper cabinets should mount to more than one beam, but as noted it's not long enough to hit two. For this reason, we recommend using fasteners liberally to join the cabinets to the ceiling panels. We've seen great success from using standard wall anchors designed for studs (The metal variant) or other wall anchors designed to open up and expand behind the ceiling panel.

    It's also recommended to use rivet nuts or similar anchoring method to join the cabinets to the horizontal beam running the length of the vehicle along the bottom/back of the cabinet.

    • Is the wood color consistent across orders?

    Lumber pattern is not guaranteed. This comes from raw lumber and varies in tint, shade, and grain. Small defects in the veneer also occur occasionally and we make a great effort not to use any lumber with serious flaws.

    The ends are made from real wood, not veneer. For this reason you may see small gaps (~0.075") at the ends and centers of your cabinet sections. These may be filled with putty, painted over, or ignored.
