1000 watt Yamaha generator?
I had an Alpenlite fifth wheel and got a Yamaha 1000 watt inverter generator when I needed a new convertor, I put in a 45 amp convertor thinking that it would be handled nicely in the rare instance wh...

Reading the above thread is why I'd like to pickup about a 40 amp converter/power supply for our RV drycamping that had a knob-adjustable voltage output of, say, 13.6 volts to 14.8 volts.
Using that I could recharge our RV's 230 AH AGM battery bank with our little Honda EX650 (around 560 VA) ultra-quiet generator ... starting out by first setting the converter/power supply to only 13.6 volts and then quickly (in maybe 1-2 minutes) turning the voltage knob to as high as possible a point just below tripping of the little generator's overload circuit breaker.
The above is how to use a small generator to the "best of it's ability" to charger an RV's battery bank as quickly a possible with an "undersized" small generator.
I think the above technique is kindof what David ("MEXICOWANDERER") has posted about so much in the past touting the use of relatively inexpensive power supplies with adjustable voltage outputs for the charging of RV batteries.
FWIW, we just returned from 6 days of drycamping. My EX650 would only supply around 15 amps continuous into our RV batteries when recharging using BOTH the RV's fixed voltage Parallax 13.8 volt converter IN PARALLEL WITH our Sears 2-10-50 battery charger set to 50 amps. The little generator sounded only partially loaded down, as it should have been able to deliver around 30 amps continuous into our RV battery bank staring at 50% SOC - if it was to be feeding a manually voltage adjustable power supply that was doing the battery charging.
