I have the Dish Traveler on my 15 38rSSA installed on the roof. Excellent piece of kit. It is installed forward and on the driver side next to the bathroom vent where the cabling is located. Make sure you leave enough room for the feed horn to rotate completely around about 6 inches from the roof because that's what the antenna does when it is in a new location and searching for a signal. It will clear the standard vent covers but if you have the rain covers over the standard cover than it could be a problem.
