Imagine the freedom of powering your portable grill, heater, or stove directly from the propane tank on your RV or patio, all without the hassle of running out of fuel mid-cookout.

My journey to this product started with pure frustration. Countless camping trips were marred by the dreaded “click, click, click” of an empty propane cylinder at the most inconvenient times.

Real-World Testing: Putting Marshall Excelsior MER470 Flow Longer Propane Kit to the Test

First Use Experience

I first tested the Marshall Excelsior MER470 Flow Longer Propane Kit on a weekend camping trip in the Appalachian Mountains. The primary goal was to power a portable propane grill and a small propane heater from the RV’s main propane tank. Setting up was straightforward. I connected the brass tee to the RV’s propane tank connection, then attached the hose to both the tee and the portable appliances.

The weather was typical for the mountains: cool and damp, with temperatures dipping into the low 50s at night. The kit performed admirably. The propane grill fired up instantly, and the flame was consistent, even with the main RV furnace cycling on and off. There were no noticeable pressure drops or interruptions in the fuel supply.

The initial setup was simple, though I did need to ensure the POL fittings were securely tightened to avoid leaks. I also realized the importance of having a good set of adjustable wrenches for tightening the connections properly. There were no major issues, only the slight initial fiddling to ensure a leak-free connection.

Extended Use & Reliability

After several months of use, the Marshall Excelsior MER470 Flow Longer Propane Kit has proven its reliability. I’ve used it on multiple camping trips, backyard barbecues, and even during a power outage to run a propane space heater. The hose shows no signs of cracking or wear, and the brass fittings remain corrosion-free.

The durability is impressive. Despite being exposed to sun, rain, and fluctuating temperatures, the kit continues to function flawlessly. Cleaning is simple, requiring only a wipe-down with a damp cloth to remove any dirt or grime.

This kit significantly outperforms my previous method of relying solely on disposable propane cylinders. The consistent fuel supply and the elimination of constant cylinder replacements have made my outdoor experiences much more enjoyable and cost-effective. It definitely exceeds my expectations for convenience and reliability.
