Camco Extend-a-Stay 3 port T Anyone installed it?

We used the T by Marshal Brass for about 12 years on 3 different coaches. We used it for the ability to use an additional propane bottle to run things while parked for a longer period of time. It was a great addition. We never had any difficulty with any propane appliance in all that time, including stove, 2 furnaces or fridges. It worked great. You will enjoy the convenience of filling up a 30 or 40lb cylinder rather than unhooking and driving to fill up the on-board tank. Hope this may help, Happy trails Bert.

Good flared connections generally cure leaks or in some cases some teflon tape or LP compatible pipe dope may be needed.

Many users who encounter low flow issues are using too small of a cylinder to supply the demand. A 20# cylinder will not vaporize the liquid propane fast enough in cold weather to keep up to some furnace requirements, especially when something else is drawing at the same time, like the hot water tank or cook top range, etc. Using 30 or 40# cylinders usually will cure the problem.

Beyond that rambling answer, looking at the part from Camco, I don't see how you are going to cure your problem with it. The item you are looking for is an extend a stay fitting that installs between the on board tank and the on board regulator and allows connection of a separate cylinder to feed the system.

I too use the Marshall Brass Extend-a-stay.. Alas, they no longer make them.

There is one common issue I have read about. This is easily fixed. I do not know if it the tank or the adapter that has an excess flow valve,, If for any reason there is no pressure in the lines, and you have enough line. then when you open the main tank valve this excess flow valve will seat and shut you down.. The solution: Turn off tank valve, Enjoy a cup of electrically brewed coffee.. SLOWLY open valve till a person with good hearing just hears gas start to flow.. When they can no longer hear it, open a bit farther, and farther. Till it is fully open (never leave it partially open for more than a few minutes).

NOTE: the Extend-a-stay should not affect flow to furnace or stove. (or anything inside the RV) unless that excess flow valve slams shut.

Flow to the grill (or from an external tank) however MAY Be restricted.
Folks with "Monster Grills" often report low flow issues.

And though I doubt there would be low flow from a portable tank with the gas coming out at around 200 times the pressure delivered to the furnace.. I can imagine it could happen.

Unless I copied the wrong part no. that is what this part does.
Already installed and hooked up to a 20lb cylinder. I tested it by running a stove burner, fridge, water heater and furnace. Of course it is pretty warm here, 80 deg. Since we are full time, our plan was to fill the on-board tank next time we exercise the RV but run off the 20lb tank. The T came with a 5 ft hose and a 12 ft hose for a campstove or barbie.
Thanks

Thanks for the tip :)

This T does have excess flow valves but no problems so far. Could be that was the problem the Amazon buyer had. There seem to still be some of the Marshall t's on Amazon and Ebay but just the t is 100.00$

Take care.
