Flatbed tray

Also called ute tray, truck tray, tray bed, flatbed conversion, aluminum tray, tray back

A flatbed tray is a flat open deck, usually aluminium, that replaces a pickup's factory bed completely, trading the tub's walls and wheel arches for a wider level floor with storage boxes hung underneath it.

What is a flatbed tray?

The factory bed unbolts from the frame as one piece, and the tray bolts on in its place: a flat deck sitting above the rear wheels, a headboard protecting the back of the cab, and sides that drop, lift off, or are absent entirely. Because the deck rides above the tires rather than between them, there are no wheel arches in the load floor, and the floor runs the truck's full width where a bed tub gives up inches to each wall.

In Australia this is not a modification but the default. The working version of a ute, the vehicle Americans would call a pickup, commonly leaves the dealer wearing a tray, and Australian aluminium tray makers have been refining the pattern for decades. One of them, Norweld, now builds trays for American trucks, and the Tundra in our build notes wears one. In the United States the same object reads as exotic or as a work-truck part: an Australian ute is sold as a working chassis that takes a body, and an American pickup is sold as a finished consumer vehicle with a styled bed.

What it buys

Geometry, mostly. The space beside and below the deck, which a factory bed encloses in styling, becomes under-tray storage: toolboxes and drawers hung beside the frame rails, carrying weight low and opening to the outside of the vehicle. The same gear in a bed tub sits higher, stacked behind a tailgate, reached by climbing in. A flat deck also mounts a camper flat, without the dead air a bed tub forces underneath a slide-in, which is why flatbed campers exist as their own category. MAK and Owen, whose Tundra gave up its bed for a Norweld tray, praise theirs in exactly these terms: what the built-in rear drawer changed was how easy the gear is to get at.

What it costs

Weight and money before anything else. Norweld's Australian page quotes its Tundra trays from 260 kilograms, about 570 pounds, as an approximate figure; its US brochure baselines full-size trays higher, from 635 pounds, and neither sheet says what separates the two. Boxes and drawers ride on top of either figure, and the maker's own advice is to weigh the vehicle after fitment. Whether the finished tray comes in above or below the bed it replaced depends on both of them, and the scale is the only way to know.

What it does not buy is capacity. GVWR and the axle ratings were certified for the truck, and they do not move when the body style does. A tray carrying a camper is the classic case of a truck under its GVWR and over its rear axle rating, because nearly everything the conversion adds sits on or behind the rear axle.
