Inverter Generator VS Regular Generator

I am running 2 6 volts and I have a 1000w generator. When the batteries are discharges the converter draws too much and the generator can't handle it, and the battery charges I've found locally don't put out enough to effectively charge the battery. I agree about the noise, I find my little generator annoying. I can borrow my Dad's generator which is a Champion for our trip and see how it does. I am also being conscious about weight because I am running pretty close to my GCVWR as it is and the inverter generators appear to be lighter.
