Fellow GMC'ers
so I am having a small issue and that is i don't want to rely on the 6500 Onan anymore. The noise and exhaust is just too much. I have seen the option to change out to the generac and the honda of which these items are no loner being made. OUr registeries and help sections are out of date and seems, call it the economy, is removing our sources from the industry. Has anyone out there used another brad or retro-fitted to another type. if I find one I have an original onan to get rid of.
thanks

At least one person has purchased a "run-of-the-mill" generator set, disassembled it into its major components and reassembled it into the generator compartment. Most of the off the shelf gensets (as you see at the big box stores} are air cooled and may not be electric start.
Jim Bounds is doing some work with using the small inverter types that are made by Honda, Yamaha and others. I've even seen them at Harbor Freight. You might read his posting on his web site about his luck. He did a slide out with 2 of the small Hondas. No idea if he is still chasing that dream. It would be nice because their price point is low, and they are everywhere.
Honda ev6010s are readily available and parts, expensive as they are, are easily obtained. Major re-builder in Florida has them. He is where Jim Bounds gets his for customer installations. He repaired two for me.

With Miguel's long distance help, I installed a Generac Primepac in my coach, but these are not available anymore. Seems there are not a lot of RV generators out in the marketplace these days other than Onans.

PO installed an Onan 2800 watt in my coach. It runs the AC and microwave at the same time. Fits the compartment nicely, has remote start and has been trouble free.

If you can live with only one AC unit, then get two Honda EU2000i's and parallel them. That's 4KW total, and when you don't need AC, you only run one. Nice and quiet.
Pinellas in Florida also has electric start upgrades for them. Store them and a 6 Gallon gas can in the Onan Compartment if your house batteries are not in there.
Yamaha makes similar units.
Two will cost you only $2K with the parallel kit, but only gets you 30A (26, actually) but enough to run an AC unit.
I've seen people connect more than two of these together on You Tube, but that is not sanctioned by honda. Don't know if it works well or not.

Pinellas also has a very slick remote wireless start fob for the Hondas. Great guy. He even has a large number of YouTube videos on the Hondas. He is really about sharing the information.

Thanks I have made contact with Paul Wolaver, currently his stock is out. I will probably give Gary Worbeck a call and see if he has any insight on his generac. Seems we are out of luck. I only have one AC and it works well. Maybe the two small Hondas are the key. Seems we are out of options on our coaches. I'll keep checking back in case there is new developments

We have the Generac 66G in the stretch, set up for 240 VAC thru an auto transfer switch. It was installed in 1997 when the coach was built and has just under 200 hours on the clock. The only problem I had with it was the LOPSD switch failed and wouldn’t allow the unit to start. Simple fix, runs great, can run both air units together and the HW heater at the same time. Quiet unit, much quieter that the Honda, but much harder to find.

Is there a good way to plumb into the ex gens fuel supply? Would you just connect it through the shore power cable?
The generator is the biggest reason I am considering selling my coach. I won't put $4K into a new generator for something I only use 3 times a year, but without the generator I won't even use it that much.
How do those little boxes tolerate heat?

I'd hang my voltmeter across the compressor leads. If the genset will spin the compressor off, and if after it starts it measures over maybe 105Volts, you aren't probably going to hurt it. I'd then check the running load on the genset, and if it's within spec, you probably aren't going to hurt it either. If it takes more time than normal to start the compressor when the 'stat calls for it, you >may< hurt it and/or the genset.
We use the little inverter gensets for remotes where the load is constant - lights, sound system, etc. We use fixed speed - mostly contractor gensets cos they are cheap albeit noisy - where we start electric motors repeatedly - A/C, pumps,, etc.
For mission critical we use mostly Onan or Kohler 'hospital package' systems which come up to power in 4 - 6 seconds. On the shared with TV sites, big Caterpillar or EMD systems. I like the EMD where you need that much power, slower turning BIG Diesels sound nice when they're pulling a load. One building we were in was peak shaving with the local utility using a Cummins/Onan megawatt plant which gave a lot of engine mechanical trouble. My Cummins/Onan tech said they made a 750KW into a megawatt by running the boost on the engine up, which it didn't like at all.

Steve,
The specs I found online for the 15k Coleman Mach 8 "Standard Running Watts" is 1483. The Honda (and Yamaha, which I have) "rated" output is really only 1600 watts. So, that doesn't leave much left for starting capacity, which is at least 1.5x the running watts, but might be 2 or 3x the running load. So, my guess is, as soon as you turn the a/c on, the generator's automatic overload protection will kick in, and the generator essentially won't produce any power. So, it probably won't hurt your ac unit, but the generator might not like it much.

Have tried running a couple different campers a/c. (Including my original unit on my gmc) On honda 2000. Overload kicks in on startup. Father in laws bumper camper. And another friends 5th wheel.
I have heard talk of adding extra start up capacitor on a/c to get them to run on the 2000 honda units but do not personally seen that approach in action.
I also know one guy who has an a/c unit on truck camper that is run on a 2000 honda, but itbis only a 9600 btu unit.

Randy, What is wrong with onan?
Other things i have not tried, is running a indoor a/c on the 2000i.
Like: http://www.amazon.com/gp/aw/d/B0022MNFUG/ref=mp_s_a_1_13?qid=1412730949&sr=8-13&pi=AC_SX110_SY165_QL70
Otherwise the dometic 3000 has been known to work like having a honda. Just not sure long term reliability, and it is a bit heavier and louder. But for the price, it might be an option

I still plan on buying a new atwood roof ac next spring:

Been out for a bit having too much fun and can't right now take the time to
read this entire thread but I have done some pretty extensive study on this
subject.
The roll around AC in the last post may in fact work on a Honda eu2000 but
I can't as yet figure out where to put the thing and not loose anything
else in the coach. The Honda will run an 8500btu Coleman roof AC, did it
in a VW bus AND run the converter but nothing bigger. The Dometic 3000
WILL run a Pinguin 13.5K btu roof AC but just barely when the converter is
on but I'm still not sure if it is reliable. Delivered 1, it worked then
it didn't.
All that seems to be batted around is around the edge of a "minimum
standard" but still I have to say for the cost and the fact that it will
just work for sure is to get a Honda EV-6010 or 4010, get it checked out
well and when it's in you will have power. I know this because I do this a
bunch.
I'm always open for suggestions because that's the only way we can get
better.
Good to be back, will take a while to get reintegrated. I wanted to thank
all of those at the Mantica rally-- man it was great to get away and
friendships there are forever. WS just knows how to throw a party!
