RV Propane Tank Cover Diagram: Dual 20/30-lb Shells, Access Lids and Parts

Replacing an RV propane tank cover starts with identifying whether it encloses one cylinder or two, and whether those cylinders are the 20-lb or 30-lb size. A damaged lid may also be replaceable without buying another complete enclosure. This illustrated guide compares Camco and Flame King cover designs and connects each part number to the corresponding product photo in NewRVParts.

What makes up a typical dual-cylinder cover setup?

The external shell is separate from the cylinders, their hold-down hardware and the LP-gas regulator. A cover's access hatch is intended to reach the valves or indicator without removing the whole enclosure; the exact hatch design differs by manufacturer.

2 — Valve-access lid or hatchesCamco double covers use a hinged access section; Flame King YSN-PCC-RV30 has separate top ports
3 — Cover-to-rack clearanceCheck width, depth, height and the existing mount arrangement

Camco 20-lb and 30-lb double-cover numbers

Camco's 20-lb double-cylinder covers are 50502 black and 50503 white. For a pair of 30-lb cylinders, its corresponding models are 50512 black and 50513 white. Camco 40564 is different: it covers just one 20-lb cylinder.

For a different access design, the Flame King YSN-PCC-RV30 is a black, dual-30-lb polypropylene cover with individual top cylinder-valve hatches and a side regulator-access port. Flame King lists outside dimensions of 29 in wide × 14 in deep × 25 in high for this exact model. Measure your space instead of assuming another manufacturer's cover has the same footprint.

Choose by the actual installation. Cylinder weight class alone does not establish fit. Confirm cylinder count, cylinder height, rack width, centre hold-down rod, available surrounding clearance and access to the regulator. A cover should not obstruct required propane-system vents or prevent access to shutoff valves.

When is a replacement access lid enough?

Camco 40549 is a black replacement cap kit for a compatible new-style Camco double-cylinder cover, rather than a whole outer shell. The elongated cap is designed to provide access through the top opening, and the listing includes attachment hardware.

Before purchasing the cap, compare the existing lid's outline, hinge and attachment points. Do not assume it fits every Camco 20-lb or 30-lb cover—or a Flame King enclosure—just because the colour or cylinder capacity is the same.

For repairs underneath the cover, follow the component rather than the shell size. The regulator and hose guides explain the cylinder connections and two-stage changeover layout.

Manufacturer design references

See Flame King's YSN-PCC-RV30 cover details for its dimensions and access ports. The Camco 20-lb double-cover reference illustrates the hinged access arrangement. For the replacement cap, compare your installed cover with the exact Camco part before ordering.
