Champion Stand Alone Generator use in rainy Weather.

Thanks for all of the Input. I am still deciding what I am going to do, I have a 35000/4000. It will not be used in a Campground.
Is it Possible to route the Exhaust through a Hole in the big Compartmenet under the front of my my 5th Wheel with a Pipe of some sort to vent Exhaust Gasses away from the Trailer and run it inside that Compartment with the Door open so it gets enough Air Flow? I can fix the Door at an Angle so the Rain would not be an Issue, and still allow for adequate Air Flow.
