on board generator

Think about the noise aspect being installed inside the trailer and the exhaust fumes if the wind is blowing in the wrong direction and the windows are open. I usually cable lock my Honda2000 to a tree a short distance away, pointed away from us and other campers so as not to be easily heard. And stored/hidden when not being used. I had a Class C with an onboard Onan. It was really useful for having power when traveling down the road but the noise and fumes were pretty bad while parked. I did use it a couple times at night to run the A/C while boondocking. But my Honda could do that in a pinch if I turn off all other loads.
