Yes there are adjustments for both in and out. Newell applies a 7 second count as it moves rule when adjusting them for quietest operation and least slam. The midship control valve is accessed by removing the laminated angled panel on your laundry to bedroom wall at the ceiling joint, which is just right of the top of the door. There is an adjustment screw head for both directions on the valve and it just takes some time to get it right where you want it. The back bath door is a bit harder to get to and you must remove a few pieces of the upper wall over the bath door to get to it and depending on how your coach is laid out different from mine and it's age , they may be located a little differently. I learned about mine at Newell with a guy from production, who installs them showing me how it's done. You may want to have them do it if you don't want to take panels apart.
I can show you in Arkansas if you wait til then... Larry
