Adding a temporary propane cylinder to an RV can involve very different parts depending on whether the vehicle has a permanently mounted motorhome tank or removable trailer cylinders. This reference separates Camco motorhome propane supply tees from MB Sturgis Sturgi-Stay and Type 1 Sturgi-Flow components, then links to exact UsedRVParts catalog listings.
First identify the RV's main propane supply
A fixed motorhome tank and a travel trailer's pair of removable cylinders use different valves and feed arrangements. A connection kit designed for one is not automatically suitable for the other.
Permanently mounted motorhome tank
Removable-cylinder towable RV
Camco 59103, 59113, 59123 and 59125 motorhome tees
| Camco MPN | Supply fitting | Included hoses |
|---|---|---|
| 59103 | Three-port motorhome propane tee | 12-ft portable-appliance extension hose |
| 59113 | Four-port motorhome propane tee | Tee only; hose must be selected separately |
| 59125 | Four-port motorhome propane tee | 5-ft auxiliary-cylinder supply hose |
| 59123 | Four-port motorhome propane tee | 5-ft auxiliary-cylinder hose and 12-ft portable-appliance extension hose |
Both 59123 and 59125 are four-port configurations with a 1/4-inch inverted-flare auxiliary-cylinder connection, but the included hoses differ. The 59113 is the fitting-only option. A similarly sized generic supply hose is not proof of a suitable replacement.
The Camco 59125 item is present in the UsedRVParts catalog but may currently be out of stock; review the live listing before planning an installation. Parts shown on this page are for identification whether the current listing is in or out of stock.
MB Sturgis Sturgi-Stay versus Type 1 Sturgi-Flow
MB Sturgis 103602-MBS is a Sturgi-Stay supply adapter intended to permit an auxiliary propane cylinder to feed a compatible system. Its catalogued connections include female POL and a 1/4-inch female inverted flare, and it is not simply a low-pressure BBQ hose.
For suitable removable-cylinder RVs, 103603PKG is a Type 1 Sturgi-Flow fitting offering a high-pressure accessory branch at the cylinder-side connection. The separately packaged 103607PKG includes the Type 1 Sturgi-Flow fitting and a 12-foot bulk-adapter hose. The kit suffix does not mean the part is interchangeable with a motorhome fixed-tank tee.
103615-MBS is a different auxiliary-cylinder quick-disconnect tee listed for selected fifth-wheel or travel-trailer applications. Match its #600-thread connection, coupler and the exact upstream regulator/hose arrangement with the manufacturer's instructions rather than treating it as a universal adapter.

Manufacturer part information
Camco's motorhome LP-gas connection family identifies multiple tee packages with different included hoses. MB Sturgis describes the Sturgi-Stay and Type 1 Sturgi-Flow auxiliary-cylinder accessories as separate systems. Product identification is only the first step; use the vehicle manufacturer's LP-gas service guidance and a qualified propane technician for any installation or pressure testing.
