The Stromberg Carlson CC-255 Trailer Tray mounts above the A-frame of a compatible travel trailer. It carries up to 300 lb of secured cargo, subject to the trailer's own frame, tongue-weight and towing limits. The factory diagram labels the tray, support tubes and brackets as Figures A–I, with hardware identified separately as Figures J–O.
Open the official CC-255 illustrated assembly and parts diagram (PDF). The drawings show exactly where the numbered components fit on the trailer tongue.

Tray dimensions and trailer fit
The 2023 manufacturer drawing shows a tray approximately 32 inches across its broad edge, 19½ inches deep overall, and 24½ inches across its narrower end, with angled side sections. This is not a plain rectangular tray. The installation can accommodate many A-frames roughly 14–55 inches wide, but the tray's position, frame profile, existing propane equipment and tow-vehicle turning clearance determine whether a particular trailer is suitable.
The CC-255 hardware brackets fasten to appropriate trailer frame members. Before drilling, the maker directs installers to check for wiring, batteries, propane equipment, equalizer brackets and other obstructions. Cargo must be secured using suitable tie-down points, and tongue weight must remain within the trailer and tow vehicle limits.

Before purchasing or installing
- Measure the A-frame members, trailer-body clearance and available turning space. Confirm that the trailer's structure and tongue-weight limits can support the loaded tray.
- Identify which parts are missing from the original assembly by the factory A–O diagram before ordering individual replacements.
- Check the access requirements for propane cylinders and their valves, and preserve safe access to the tongue jack.
- Follow the manufacturer's two-person installation, drilling, fastening and cargo tie-down procedures. Verify all hardware is secured before travel.
