Sorry, not to jump on the bandwagon, but a $500 generator is a very poor long term option. They are not even made to last many hours of continuous use, are loud , and suck fuel. As far as your question, keeping it cool in the enclosure made for an RV gen is gonna be hard if not impossible. If you're dead set on making it work, most likely will need to cut out the center of the door and install louvers at the least. You can wire up a fan of some sort but make sure you also come up with some ducting to draw fresh air into the space. Blowing the hot air already in the enclosure around will have little effect.I wish you Luck, but I'm skeptical that you'll ever be happy with it. Good Luck anyway!
