The Stromberg Carlson CC-220 Gen Secure II is an aluminum storage enclosure designed specifically for installation on the CC-255 Trailer Tray. The enclosure ships for assembly, with separate panels, a hinged top, tie-down brackets, reinforcement braces, draw latch and gas shocks. It is not a stand-alone cargo tray or a generic bolt-on generator cover.

View CC-255 trailer-tongue cargo trayImportant distinctions before buying
The CC-220 enclosure requires an installed CC-255 tray and must not be mounted directly to an unsupported trailer tongue. Stromberg describes diamond-plate aluminum panels, interior tie-down locations, a latching lid and a locking plate (padlock not included). The manufacturer illustrates storage for certain portable generators, including the Onan P4500i, and some propane-cylinder arrangements; the exact equipment dimensions, ventilation needs, loading and clearances must be checked.
CC-200 and CC-220 are different enclosure generations. Stromberg explicitly identifies the parts advertised for the older CC-200 as unsuitable for the CC-220. Select replacement panels and hardware from the CC-220's own 8603-series and 1CC220-series component list.
Generator ventilation and installation
Stromberg instructs users to keep the CC-220 lid open when a generator is operating and never block the drainage/ventilation holes in the CC-255 tray. Operate any generator outdoors with adequate exhaust clearance, follow the generator manufacturer's ventilation and carbon-monoxide instructions, and avoid running an engine or generator in an enclosed space.
- Confirm the CC-255 tray is installed correctly, its mounting hardware is sound and its available capacity allows the enclosure plus cargo.
- Lay out the numbered panels and separate hardware kits before assembly, and protect hands at panel edges and hinged areas.
- Use the official assembly sequence for the side channels, rear panels, hinged lid, gas shocks, front panels and seals.
- Check lid operation, latch engagement, propane access, weight distribution and tow-vehicle turning clearance before travelling.
