X2 on buying a Gen-turi gen exhaust if you plan on a lot of boondocking.
It will keep most of the exhaust from entering your MH. Plenty of openings under the coach and all the windows have weep holes for exhuast to find it's way in. Maybe not enough to kill you but it WILL give you all headaches running it 24-7's.
Personally I will not sleep in a MH with gen on without a window cracked open.
Seen too many fatal accidents and coincidentally they were at sporting events and horse shows.
Most MH's will shut off the gen when the gas gauge on the MH hits 1/4 tank. Mine shuts off way before it hits 1/4. So be mindful how much gas you have in your fuel tank.
