Yes, you can. I would advise:
1- Open that window when the wind is blowing away from that side of your coach.
2- Buy a Carbon Monoxide (CO) detector, so you will know if exhaust starts accumulating in your coach.
This is unlikely if you have all the windows open, but it won't hurt, and it can come in handy if you have a previously unknown exhaust leak in another LP-powered appliance.
