A.R.E. Deluxe Commercial Unit (DCU)
All-aluminum work cap with full-length side doors, built for tools and trade stock.
Truck CapThe DCU is A.R.E.'s baseline commercial cap. The frame is .050-inch aluminum, TIG-welded, and the outer skin is .035-inch aluminum, so it stays light enough not to eat your payload. Full-length side doors mean you reach the middle of the bed from the curb instead of climbing in over the tailgate.

The line beside it
Where these 3 actually differ:
| Specification | A.R.E. DCU | A.R.E. Diamond Edition DCU | A.R.E. DCU MAX |
|---|---|---|---|
| Body | .035in aluminum skin on a welded frame | .063in diamond plate on a welded frame | .063in aluminum skin on a welded frame |
| Finish | Baked enamel: white, black or silver | Polished diamond plate | Baked enamel white as standard |
The same on every one of them
This is the entry point of the three commercial aluminum caps, and the only thing separating the three is the skin. The DCU uses a .035-inch smooth aluminum skin. Step up to DCU MAX and the skin nearly doubles to .063-inch. Step up again to Diamond Edition and it is .063-inch polished diamond plate. The .050-inch welded frame, the doors, the handles and the 3-year warranty are the same on all three. Pick the DCU if you want the lightest one and do not need a thicker skin.
Trades and fleets. Plumbers, electricians, HVAC, service techs, utility crews. Anyone who works out of the bed every day and needs the load secured, dry and reachable from outside the truck.
