Personally, I'd go big on the generator as I would use it for other things. But the 1000 watts is plenty to charge the batteries...no microwave, coffee pot or hairdryer, etc though. And the 1000 watts is lighter and sips fuel.

At a 10:1 ratio 12v DC current to 120v AC current, you'd have well over 70 amps available to charge the batteries on the 1000 watt genny. Assuming 100% efficiency and no other loads.
I'm confused :what: "doesn't take much"
A 1000 watt gennie assuming it's "1000 running watts" will only put out about 9 amps.
A normal wfco or progressive converter can and will draw up to 8 amps especially charging two batteries.
Am I missing something?

Turbs, that's 8-9 amps @ 120vac. As I said, a 10:1 ratio, that would be over 70 @12vdc to the batteries. (Can't ever be 100% conversion from ac to dc)

Real world example of what a 1000 watts of 120vac will get you: the 60 amp (@ 13.6 VDC) Progressive Dynamic PD9260 is spec'd at 1000 watts @120vac.

No problem, I don't mind a challenge as it forces me to explain a bit or to realize my errors.

I have both of the Honda 2000's and built an extended stay tank, because where we camp in summer we (dh) needs A/C during the day while I'm off tending to the car. I, would as Herk stated, buy the companian first because of the plug-ins. At evening time and early morning, I use an pure sine wave invertor for approx. 3 to 4 hours and haven't run out of battery yet....only have 1 12volt!. The converter charges just fine.
