I do believe you.. but.. with my luck, the highway patrol trooper would say something like "Is that so? Well, go ahead and explain it to the judge!"

Hvbuzz, thanks for your mention of your setup. What do you use to power that A/C while traveling? A generator, obviously, but what kind and with what housing etc to keep the noise down?

Re: Lets talk AC again

I bought a yahama 2800inverter W/boost. Love it and hate it. Hasn't worked how I had hoped it to. Might check out the last two pages of my thread. viewtopic.php?f=9&t=6481&start=105 It powers everything I need, and is really fuel efficient and super quiet. However, I've tried a couple different ways to mount it to the bus and it refuses to run while running down the road. The only place it runs going down the road is on my car trailer. This last trip was a family trip, and not a "jeeping" trip. So I had no intention of draging the jeep along, but I had to drag the empty trailer, just so we could have AC in the bus. Just found out from a couple other members some of its other problems as well. Before I bought it I was contemplating between it and a Honda. But I really don't think the honda 3000eu would be enough for all the start up loads, where as the yamaha can do it for its size. So.... as much as I hate the thought of it, I think I'm going to try and find a used onan big enough to run the AC for going down the road. Then use the yamaha after we are there.

Re: Lets talk AC again

Family wagon,
I read earlier you had a 2000eu. Are you able to parallel that one with another? That might be ideal for you since you already have one!?!

Re: Lets talk AC again

Hvbuzz, thanks for the insights on your Yamaha. It's interesting; I've tried running my EU2000 on a hitch carrier as well. The engine never died (sounds like that was the problem you experienced) but I did have trouble running a little A/C. Looking back, it's probably because the refrigerator was running and there wasn't enough capacity left over to start the A/C compressor. I hadn't even considered that road vibration would affect the carburetor -- the thing vibrates so much as it is!

Paralleling is an option for mine and is one of the main reasons I picked the EU2000. My bus has an Espar diesel boiler and I may configure that with a heat exchanger for heating hot water, which would leave cooking as the only consumer of propane. I'm thinking about going to electric cooking in order to lose the propane (don't want to carry and store 3 fuels), but the problem I'm facing now is how to run an electric range off a generator: parallel EU2000 would have enough power, but it's going to be at 120 volts. A step-up transformer looks to be $400+. 240 volt output doesn't show up on inverter generators until about $3500 price level -- too much. Maybe, like you, I'll have to do two generators so that I can have one large for running A/C and cooking, and one small for everything else.

Back on the A/C.. Since my bus is completely empty it looks a lot like a moving truck. I've been asked to help a friend move some stuff tomorrow, and that involves about 5 hours of driving.. Tonight I'm going to get a couple sheets of OSB and build a wall to hold that window A/C where I hung the tarp curtain in my earlier test, and I'll strap the EU2000 to a hitch carrier again, and we'll see how that A/C and genny do during tomorrow's trip. It couldn't keep up with the scorcher of a day we had two days ago, but even then I suppose it's still better than the alternative and anyway it isn't normally that hot (so the benefit would be even better).

I thought it was alright. An exterior roller shade, essentially. But at a very affordable price.

Re: Lets talk AC again

Sorry to those from turning this from a AC talks to generator talks. I'm thinking it goes somewhat hand in hand though.

Family wagon, sorry I really don't know how to quote old posts, I think you are going to stumble onto the problems I have been having, and not sure how to fix. On my generator, the engine never dies as its going down the road. Like what you just said the overload comes on and kicks out the electic. But I for one know that I havn't overloaded the genny. Because it will run everything just fine, while not in motion. I'm just going to make a guess and say yours might do the samething tomorrow even with just the ac running. My advice is take some small elec load with you(like a small fan). If the genny won't power the AC, see if it will run just the fan, as you are going down the road. This is only my opinion on what I think is happening. These inverter type gennys are suppose to only put out clean power wave. So I'm thinking when they are getting bounced around, they can only put out what is clean power, and that's not the advertised rating. Unlike an onan or cheaper gennys that will put out whatever voltage and they don't care. I think I have found the smooth spot on my car trailer to where it is just right for the genny to keep running. On our 1400mi trip with no vehicle on my trailer and only the genny, it only kicked out once. After hitting a very good size crack in the road that I think might have had a small VW in the bottom of it. Or... it may all just be my generator sucks, and it was the worst money I've spent to date on the bus. Either way, I want to hear the out come of your moving trip.

Re: Lets talk AC again

Once upon a time, on an rv forum that I do not remember, there was an rver who had the same problem eith their generator. It was not an rv unit but I think it was one of those Honda ones. It would run while not moving. But stalled out while traveling down the road. I think it was decided that the fuel was sloshing and the pickup was picking up air. I think they tested the theory by using a full auxillary gas tank like used for boats. The cheap plastic ones you can buy from Walmart.

But I may be wrong.
