Just saying, there is no generator that is quiet and the hours are limited. The OP can get by with the upgraded batteries for the few nights he is talking about. He could add a little solar if necessary and that is truly a quiet power source. My point is, if he cannot run a generator, why purchase one. If he wants one to use at Walmart or truck stops, the Champion will provide plenty of power. Comparing the Champion 3500/4000 at 68db to a 80db construction generator is comparing apples to oranges.
