Since I don't know what you are calling "very cold" my comment may not apply. However remember that propane vapor pressure drops in cold weather so you have less propane flow available to you. One chart I have shows a 30lb cylinder that is 25% full will flow 32,000 BTU per hour at 60F and only 10,000 BTU per hour at 0F. Before relying on a propane powered generator you might investigate the propane usage of the generator and furnace combined if you plan to run off the same tank.

We travel regularly in sub zero temps so carry gas generators as back up.

As a matter of fact, we are planning a trip to Alaska in May, June and July. I was thinking nights in the 20s and 30s.

Your point about decrease propane flow is well taken. Thanks.

I would consider gas first then. You are not going to want to empty those tanks and find yourself miles away from someplace to fill up your propane. Reading the above document, it looks like running the generator plus furnace would empty the tanks at a significant rate.

15-20hrs depending on load....1.5lb

I carry two Honda EU 2000s (one regular, one companion) both with the Propane Carbs conversions on them. https://www.propanecarbs.com/honda-e...onversion.html Here in Fla we mostly need AC, not heat, and the two Hondas will deliver that. They are not capable of running the converter (a 55 amp Progrssive Dynamics) and AC and Microwave simultaneously.

I have run any tests on this configuration and posted results in various Airforums threads. To summarize some findings:

- At 1,600 watts of load (their rated maximum for sustained operation) these generators burn about 2 lbs of propane per hour.

- I can and do run both generators simultaneously at full power from the LP port on the front of the trailer (a factory feature on the 2014 EB) using a 10' CAMCO quick disconnect low pressure LP hose, a quick disconnect tee (two females and a male fitting) which I fabricated from 1/4" brass parts and the 3' hoses that came with the Propane Carbs kits.

- I was concerned that the total capacity of the LP system on the trailer might be overtaxed by the two generators. The LP port has a 25,000 BTU max sticker next to it. How many BTUs is and EU 2000? Beats me! So I ran a test. Remember this is at 80 degree Florida weather... not 20 in the Rockies... but I simultaneously ran the fridge, water heater, AC (thanks to the two Honda's) and all three burners of the stove. During the test I monitored voltage with a multimeter to see if the generators underpowered the electric system. They held 120 +/- 0.4 volts continuously.

I hope that helps.

We've had the Yamaha 2400 for about 4 years now. We don't need to run it often and have had no issues with it. It just starts and runs. Bought the converted unit from US Carburetion.

Streamracer, Do you have a thread for your trailer? I would love to see pics of how you engineered the genset housing.

Propane genertor

My understanding is 1 gallon of gasoline is equivalent to 1.3 gallons of propane.

Do you have the version that allows you to run both gas and propane or the version that eliminates the ability to run on gas? AND are you happy w/ the version you have?
Thanks, Markr

Perhaps you should consider an alternative - instead of getting a propane-powered generator and running your furnace, simply get this: http://www.amazon.com/Pro-Com-Dual-F...=procom+heater

I boondock in the desert, and the temperature drops to freezing at night. So I installed this blueflame heater. It is a convection type of heater, and heats my entire 32' AS from front to back. I do have the galley window cracked open and the vents over the stove and in the shower stall open to provide oxygen. I would add that the blueflame heater is the heater of choice among the boondockers I know.

I'd be interested in learning more about this. Could you start a new thread and show where you mounted this and how you tapped into the propane lines?

Thanks, Markr
We have the 2400 that was converted to tri-fuel. It works great. I use only propane though as I don't want or need to carry gasoline. It always starts on the third pull and will run the hair dryer, microwave and the air conditioner. Not at the same time though!

do you have the thermostatically controlled version? and if yes, w/out a power hook up, how does it "re-ignite" on it's own? or does the output just drop way low when the trailer is warmer than the set temperature? . . . or does the thermostatically controlled version need power?

thanks, markr
