Hello,
By now a lot was recently written about generators. But what is the best up to 2000 watts geenerator with the cleanest power output, low noise level, fuel consumption, longest life, best weight to power output ratio and the best for charging the batteries ( I am gravitating to selecting OPTIMA YELLOW TOP battery )? The cost is of no concern for me who will get on 6 month trip around Europe. 
Thanks in advance,
Ark
