Back to the basic question of 1000 vs. 2000 --
Per Michael's [CWCHIEF] recent post on this other thread:
http://www.airforums.com/forums/f448...ne-148661.html
that Yamaha generators can be purchased from US Carburetor, complete with the propane conversion AND with the Yamaha warranty, we are considering the 1000i, per the quote below, mainly to keep our batteries charged in the FC20. I will check our owner's manual, but my recollection is that the battery charger does not draw more that the 1000's rated output of 7.5 amps. Thank you for any thoughts on this capacity issue. The weight savings seem worth it to us.
Peter
PS -- edit -- On p. 8-23 of our manual:
https://www.airstream.com/wp-content...gcloud2014.pdf
the converter is rated at 8 amps. [p. 91/114 of the PDF] Seems like the Yamaha 1000 could handle this, albeit just barely, as the maximum draw of the converter would normally be quite a bit less than 8 amps . . . right? Thanks.

Since the 12Vdc output of most generators is typically at a constant voltage, it is possible to cook the batteries since the charge is not altered as the voltage in the battery increases. This is why the single rate cheap Airstream installed converter typically has the capability to cook the batteries.
When the user connects their trailer to the 120Vac output of a generator (and hopefully have a multi-stage converter to properly adjust the charge rate to the battery condition) the battery has the chance for a proper charge cycle and which results in longer life..
Solar charge controllers also have to be programmed to the charging characteristics necessary for the trailer's battery type.

FYI on a recent trip, the new tri-fuel Yamaha 1000 gen worked out great for our FC20. It handled both the battery charger/converter and the fridge on electric. We still have the OEM charger, and the batteries were fairly well charged already, but a new Progressive 4655 converter might overload the 1000 gen? TBD
The RPMs went up for the combined load, so guessing this was maxing out the gen, but the breaker did not trip.
The 1000 is really small for storage and very light at 28 pounds.
Yes!

It's normal for the RPMs to increase under load and does not necessarily mean it was maxing out.

Yes I realize that, but the two loads combined have to be approaching 1000 watts, right? [converter/charger plus fridge] The gen has a tachometer but I forgot to check it.
Plus I think the gen output is actually slightly less than 1000 watts.
PS edit see earlier posts re our OEM charger/converter load.

I want to buy four 1000 gen and hook them up parallel, parallel. That way I can custom exactly how many watts I need. I can use one, two, three or four or any combination of these! Have I overthought this?

You are joking right?

Why wouldn't you buy two 1000 watt and one 2000 watt? It would be cheaper and less weight.
And it wouldn't sound like a beehive.

I would only buy multiple similar gens if the mfg. already has a set up for linking them for more amps. Custom building anything is not cost effective IMO. The standard is Honda 2000 x2. I don't think Honda or Yamaha market a combined set up for 2 1000 watt units.
Plus wiring up your combination of gens could be dangerous and shocking in outcome!
KISS
Plan ahead for your electrical needs, and buy what fits.
A/C use is one deciding factor of course.
Happy Trails!

Honda also does offer a kit to parallel two EU3000iS 3,000 watt units . The two units cost more than one EU7000iS 7,000 watt unit but weigh about the same.

If you are mostly camping in the mid spring to mid fall, go solar you will be amazed how fast a few hundred watts of solar panels will recharge your batteries. If you are doing winter camping, or want a spare generator in case of power outage go with the 2k. If you really only want it for topping off your batteries for lights and such, go with the 1k, much lighter.
