We are very interested in the Gateway 3650bh and plan to live in it for part of the year. We have a campground we would love to stay at but the only site available is 17ft wide. They expressed concern that this may be too narrow for us if we have a rig with slides on both sides. Can anyone let me know what the dimensions are for a 3650 with all sides out? I unfortunately need to make the campsite reservations before we even buy the rv due to popularity Thank you.
