LP generator?

Does anyone use an LP generator? Since I have two 30 pound LP tanks on the front it seams like the logical choice, not to mention that it won't go bad. Is the cost of usage per hour much more expensive? Are there any issues starting it? What are your experiences?

I certainly understand where you're coming from. I just hate anything with gas in it sitting around for months without use.

I'm sure someone will come along with direct experience, but I can tell you that I have friends who use an LP conversion on a Yamaha generator because they have an SUV, not a truck, and they didn't want a generator with gasoline in either their trailer or their vehicle. They haven't had any problem with the LP conversion, they are happy with their purchase after 1.5 years of camping (probably 5 or 6 trips when they used the generator.)

I have a Yamaha 2400isHC that I run on propane. It starts the same. I just have to bleed the 12ft hose of air and fill it with propane when starting it. I get a 30lb fill up for around $12 on special 50% off days at CW that is about $1.69/gal I leave it in the back of the truck and run it from there.

I do not have figures for which is better. We would have to know the cost per gallon of each and the rate of consumption to compare. I use it mainly because it is better for the generator with my interval of usage.- no old gas or gummed up carb.
A gallon of gasoline produces 125,000 BTUs of energy and a gallon of propane produces 91,000. So propane would need to be 30 percent cheaper than gasoline to make the operating costs equal. Here is the consumption info from where I bought it.

I have to say that your question got me to dig. Look what else I found:


Triple-Fuel Yamaha EF2400iS Inverter Generator

This is specific to my generator so now I know the comparisons of consumption as well, thank you! Basically if I run my ac unit, I can run it for 16.3 hours on a tank of propane or 5.16 hours on a tank of fuel (1.6 gallons). In money that is $0.74/hr on LP or $0.71/hr on gasoline. That is at 72% load-according to the information. As I stated, I just run it on propane for longevity.

Great info, far more detail than I expected. I assume you're running two of these to run the A/C?

I converted a generator to LPG it works well... So far.

It is plumbed to and runs off my trailer mounted tanks.

Its common among us diesel motorhome owners to run the generator off the propane tank. Thats the way mine is set up and it runs great. I have an onan 6.5 genset.

FWIW, I don't have a generator yet, but I've done the research and will definitely get a propane Yamaha or Honda (conversion.) The purchase cost is about $300 or $400 more than the gas only model but like you, I would prefer not to carry gasoline around and have to worry about it going stale (my TV uses diesel.) It seems that the usage in terms of gallons of gas vs. propane is very similar so I don't think that there would be a meaningful difference in operating costs. Propane is just so much safer!

I have the Yamaha 2000 converted to a trifuel. My experience with portable generators(we live in hurricane country so I have some experience) is that you need to run gasoline generators regularly if you want them to start. Not so much with a propane generator. My expectation for camping was only periodic use so no gunk from gasoline was the biggest factor. I can run mine off the Airstream low pressure connection when I need it.

I have a Yamaha 2400 isHC. When I broke the unit in with gasoline I got 8.2 hours on a full tank running with a half load. I use propane now and wouldn't consider anything else.

I have a 2000w gas generator now. I want to upgrade and get one strong enough to run the A/C. After everyone's responses here, it looks like I'm going with a propane generator. Thanks for the advice.
