Glock: I think of the brass fitting section of my hardware store as the erector set from hell. However, there are fittings (not necessarily hoses) that connect any to any in the brass world. I'm the case of my setup, the starting point was the Female Quick Disconnect on the trailer. That's an MB Sturgis model 250 Low Pressure Propane disconnect. The end point was the brass attachment on the end of the 3/8" rubber feed hose for my LP conversion kit. Specifically, that's the fitting that connects to the high pressure to low pressure regulator that came with the kit and which attaches directly to the tank (as opposed to the demand regulator that is attached to the generator and acts in place of the carburetor used in gasoline operation). I believe the fitting on that hose was a 3/8" female flare fitting (flare fittings have a 45 degree shoulder to act as a seat while pipe thread (PT) are typically squared off and the threads are the sealing point. I can pull mine apart and confirm if it's important to you... however, the fittings you need there are a 3/8" male flare to 1/4" female PT. Here is a link to a range of fitting like that. Sometimes it takes a second fitting to complete the process. In this case a 1/4" coupling would be needed since these are 3/8 male flare to 1/4 male iron pipe. http://www.amazon.com/Anderson-Metal.../dp/B0070TUF7C

The other piece I needed was the male Sturgis 250 to connect where that adapter fit. Once installed (I use the yellow natural gas grade Teflon tape on joints... especially the pipe thread type since the threads are the seals... test with soap bubbles or gas leak detector which is the worlds most expensive soap bubble) connect th male Sturgis to the port on the trailer or any other QD of that type and you should be good to go.

My gen set rides on a 4'x2' piece of 1/2" plywood on wheels I the front of my truck bed under a hard tonneau. The two generators are on the outside and strapped to the board. Two 20 lb LP tanks are in the middle set in 8" holes tandem (fore and aft). The exhausts point back and controls on the front. When I need them I roll the platform to the tailgate, hook up whatever gas source(s) I'm using, connect the electrical umbilical to the trailer and fire it up. I chain and lock the generators to the truck in both the storage and use locations.

Let me know if that helps or if I answered a different question. When I'm on my PC I can post pics if you want to see that... Might save 1,000 more words.

Remember, on Alll connections....always use the YELLOW pipe thread tape, not the white. And ALWAYS bubble check for leaks.

Did I mention ALWAYS bubble check..?

For Wlanford and anyone else interested in this topic: An update!

We left off weeks ago with a question about whether the LP port on an Airstream could run two Honda 2000's under load with 1/4" brass connections and if so would other gas appliances in the trailer also run.

We are heading out tomorrow for three weeks, so I hooked up everything and ran a test. I hooked both generators to the LP port on the front of the trailer using a 10' quick disconnect hose, a tee fitting made from 1/4" brass parts and each generator's feed hose which came with the propane conversion kits (which are tri-fuel kits from Propane Carbs: https://www.propanecarbs.com/honda-e...onversion.html). That's 13 feet of flexible gas tubing and three disconnects between the port and each generator! Both generators had eco throttle "off". Only one LP tank was online. It's a 30 pounder on the front of the trailer and it is completely full.

I plugged my multimeter on the AC Volts mode into the kitchen outlet and fired everything up. The voltage read between 120.4 and 120.7 with no load (perhaps the converter was charging the batteries... but that's it).

I started the AC. It came on fine and the voltage remained 120.something.

I started the gas water heater (no heater had been running... the heater was stone cold and I checked to see that it started successfully. The burn on my fingers from opening the access panel said "yes"). No change in voltage.

I started all three burners on the range. No change in voltage.

The fridge was on "auto" so it would have added electric load, not LP during this test.

This isn't an engineering statement, since I'm not an engineer. This is a practical, user test and I had no indication that the generators were fuel starved while under heavy load and with four other LP consuming appliances running on the trailer.

Wayne,
Thank you for researching the answer to this dilemma. It has driven my husband and I nuts for months. I contacted MB Sturgis and they were very helpful and are sending the hose to a campground that we'll visit next week. Hopefully we'll finally be able to grill!!
Again, thanks for posting all the pertinent info.
Fran

When you say you ran a 10' quick disconnect, by any chance was that the Camco 57282? I'm planning to order the same one to connect my QD directly to by generator.

To xxxreme... That looks like the Camco 1/4" QD LP hose I have. Like I said earlier, the combination I run exceeds the supposed capability of my trailer's LP system... But it works in practice for me. It may not fail gracefully (like if I run an LP tank dry) or have some other issue I have not experienced yet, so I'm not endorsing exceeding the limit of the trailer's external LP port. Also, I do not leave any generator running unattended (like at night while sleeping, or by leaving the campsite).

Sounds like exactly what I need!

I am sure there are built in safety cushions with manufacturers recommended limits. I think I will pick up a Kill A Watt Meter so I can safely monitor the draw on my generator while running everything. Thanks for playing guinea pig on this one for us
