Some of the trailers in the early 70's had a way to take some exhaust flex (metal) pipe, and run it downward, from the muffler to the trailer floor, where a fitting allowed you to vent the exhaust out through the bottom of the trailer. I always wondered why the military stopped doing it. Sounded like a good way to keep the trailer cover shut, warm and the exhaust would not be drawn back into the air intake. It doesn't take long to foul up the air filter and the set WILL stop running when that happens.
