This unit on propane should clearly run a 2000watt A/C unit alone:

Or two of these in par (on propane):

Additionally, all that I've read seems to indicate that a 20lb tank of propane is the equiv of 5 gallons of gasoline FWIW. One of the selling points for me is that I don't have to lug tanks of gasoline around. I can just use the tanks on the Airstream which currently I have about 60lbs (approx) on board at any given time.

Did a search through RV.Net on whether a single EU2000 generator could power an 11,000 BTU AC. There appears to be quite a few more people who have tried to match the two - with a fairly clear pattern of results.

A single 2000 W generator has trouble with older AC's - pretty much end-of-story - in some cases just a no-go from the start, in others a no-go at high temperatures or at altitude. Any reports of difficulty just indicated that the generator wouldn't do the job - there were not any reports of damage to AC's. With newer AC's there seems to be pretty good success - folks seem pretty pleased with the match - a couple folks even claim to be runing their 13,500 BTU AC's with a single EU2000 (not suggesting this is a good idea).

I'm starting to feel more and more comfortable with the thought that a single EU2000 should will run our Bambi's 11,000 BTU AC just fine, however; still grappling with the question of whether the AC is a real need - or not. In any event, tomorrow I will be making the trek up the highway to have a look at them both again (the EU2000 and the EU1000). Will also be looking at the Yamaha EF1000iS - seem like a pretty impressive little unit - its smaller, lighter, quieter, more fuel efficient, less expensive and has double the warranty period of the Honda - I'm surprised the Honda seems such a universal choice.

Have yet to look up the information on propane conversions.

rangerjay---one thing to concider when thinking of propane for fuel--you will reduce the output of you gen as propane has less BTU's , hence less horse power, 2nd is consumption, you get less running time on a gallon of propane than gasoline. If a 2000 will barely run an ac on gas it is unlikely it will do it at all on propane. a 30 lb bottle of propane will weigh nearly as much as a second 2000.
A Honda EU inverter series generator is unlike a standard generator. It does not have to run at and maintain 3600 rpm to produce 60 cycle alternating current. Because of it's inverter technology, the engine can run at any speed and produce the same voltage and frequency. The engine speed increases to produce more current. I have not noticed a reduction in power on propane. As far as consumption, the difference is little to none on a generator that small. You will get MUCH longer runtime on a 20 or 30 lb gas bottle than the EU's 1 gallon gas tank. My Airstream has 2-30 pound gas bottles. If we are lucky, we might use 1/2 bottle per camping season, for hot water, cooking and heating. While fulltiming, the quickest I used a bottle was 8 days, with water heater running all the time, using the furnace every night, and cooking on the stove twice a day.

I followed the link but the EF2800i is not shown in the charts as sufficient for a 10,000 BTU AC.

Must be retirement – but I’ve taken more time to buy this generator than it took to purchase my last home. In any event – had a good day reviewing, on site, both the Yamaha and Honda generators – was also able to spend some serious time with a propane installer regarding conversions.

At the end of the day I wimped out on the Honda 2000 – now own a nice Airstream blue Yamaha 1000 – it won’t run the AC but seems more than adequate to do everything else. At the end of the day I just couldn’t justify the extra expense – and the 1000 is a better fit in the vehicle.

Had a great discussion regarding propane conversions. Turns out that the mechanic I was talking to had been a propane installer at Superior Propane for over 20 years – retired from that organization – and became the chief mechanic at a large shop specializing in farm equipment, marine equipment and small engines – which is where I purchased the generator. Much of the information that was available on this and other threads was confirmed – especially noted was that there is a small reduction in power when using propane – he suggested that a propane conversion was not appropriate if the application was going to be pushing the limits of the generator. Another point that I hadn’t heard before is that after-market propane conversions can occasionally cause a lot of grief – most don’t – but when they do you will very likely end up getting rid of the unit. His advice was to not consider an after-market conversion unless there was a compelling reason to do so – and if there was good reason to consider propane, and you had the opportunity, then look at purchasing a factory propane unit. As far as the desire to not carry a gas can around his advice was simple – get a siphon to take it directly from the vehicle. I found it refreshing that he was so up front with his advice – especially since his shop stood to do the conversion (he did however, convince me to put in trailer connections for the propane stove and BBQ – and get away from hauling around my littler 5 pounder).

The Yamaha will get its first test on a 6 night outing in a week or so – followed by a 5 week road trip beginning in September. Hope I’m as pleased at the end of both trips as I am now.

Only one problem - my kids have seen it - and were pretty impressed. They inherited (claimed) our old pop-up - I can see the wheels turning.

Thanks all for your help – and patience.

Jay

I'm sure the Yamaha will work fine for you. I use my Honda EU2000i to charge the trailer batteries, which your Yamaha will do just fine. I would need a second Honda to run the A/C and so far I have been too cheap to buy another one.

Speaking of propane...

Would anyone have any suggestions of what would be the best way of tapping off of the propane tanks to run a barbeque, lights, etc., so I wouldn't have to carry an extra cylinder. Is there any way to do it without splicing into the copper line?

Thanks.

Been running my 11k a/c on my 1999 25' Safari now for 2 1/2 years. I installed a hard start or quick start capacitor kit to help it get going. I agree it is marginal and usually run the refrig on gas. I turn the cmpressor off and turn on the fan to low speed. Start the gen. on high speed, not the econo. I then add in the compressor. It will run the a/c and converter ok. I turn it off when we want to use the microwave, etc. I have hooked it up to a 5 gallon plastic fuel tank and it will run a couple of days. I have used it up to 5000' but above that, it won't pull the a/c. I was going to add a second one but this has worked out fine most of the time. I want to know if it can be combined with the 1000. That should give me some extra margin.

There are some issues concerning the valves in an engine that runs on propane. Some say propane will "burn the valves up". Most of this information comes from mechanics from the leaded gas era during the 20th century. I have been told it is not an issue on a modern gasoline engine that is designed to run on unleaded fuel. Time will tell however. I have faith in modern technology. If I burn the valves in my generator, I'll just do a valve job on it.

The valve issue is no longer an issue, (Hard valve seats and stems) we run propane powered generators for backup power, sometimes they run for days on end. The longest continuous run I have seen was 8 days 14 hours. We have logged thousands of hours on propane with no valve problems. I would not worry about it. I'm thinking of converting my 2000Eu.
The issue of a tap for running the generator off of the trailer tank, try this link. http://domsoutdoor.com/category.asp?...cd2=1128275170

All of this makes REALLY good sense! I live in Virginia and started out being a "non-boondocker" but all y'all (in the south y'all is singular, "all y'all" is the plural) convinced me to try boondocking. In Virginia the fantastic fan, the endless breeze blowing directly on me, etc is still hotter than hell! I've got to look seriously at a generator - and one of the things to consider is weight! As a single woman I don't need to sprain my back woman-handling a huge generator in and out of the 2500 Burb. So what does the EU2000 weigh, and the EU3000

Or do I just time my boondocking from March thru May and October?

EU2000 = 46lbs
Eu3000 = 134lbs

I own the 2000 not really light but manageable. If you need something lighter you would have to go to the 1000 = 28lbs. It is good for charging your batteries, but that's about it.

Has anyone bought a brand of generator other than a Honda? I love the Honda brand; however, they are so expensive. I have a 24ft Argosy, with a new 13,500 AC. I know the 3000 Honda would probably pull it, but there are other generators that are far less expensive. I know about the noise feature of the Honda and the Yamaha. Is that the primary reason so many RV people buy them? I would just be using mine at the lake property and noise level is not the primary concern. Consumer Reports rates the Troybilt highly. There is also a Coleman with a Honda engine that is quite reasonable for a 5000 watt.
