It sounds like the op only uses the generator to charge batteries. I know its not a popular choice among those that run toasters and coffee pots but you may want to look at the small 1000w inverter gensets or even the 800w. They will handle most trailer and small class c converters as long as you are just charging batteries. They weight about 30 lbs and are 2 or 3 db quieter. They are also cheaper by several hundred dollars than the 2000w units. If you could get by with only using a gen a few times in several months these may be a better more economical choice.
