Yes, running the generator while on the road is common practice. On my 5th wheel trailers I liked to run the generator to cool things off about an hour before arrival. Opening the compartment door won't do much. My current generator is enclosed in a sound insulated box with a vented door and the generator has its enclosure of course. My other larger trailer just had the generator in the front compartment, no sound box and it was less noisy. The difference between the current 4.0 KW and previous 5.5 KW is substantial. Smaller one is a good bit louder, I only run it when I really need to!
