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.
