It’s designed to offer flexibility, allowing connection to auxiliary propane cylinders or tapping into the RV’s system to fuel high-pressure appliances. This kit aims to solve a common problem: running out of propane at inconvenient times, impacting everything from heating to cooking.
I’ve experienced the frustration of a cold shower halfway through a camping trip due to an empty propane tank. I was looking for a reliable solution to extend my propane supply without hauling multiple large tanks. The prospect of linking additional cylinders or using my RV’s supply for a portable grill caught my attention.
Unboxing the Marshall Excelsior MER472 Stay Longer Propane Kit revealed a solid brass tee connection and a sturdy-looking hose. The brass components felt reassuringly heavy, suggesting quality construction. The hose, though not overly flexible, seemed durable enough to withstand outdoor conditions.
