I took the time to lower the side rails on mine today and it worked out real nice. Looks allot better when rolled in. The top motors are now somewhat flush with the top of the camper roof line, where before the motors were sticking up some. When rolled in the fabric is now pretty close to level where it mounts to camper instead of being higher on he roll tube side. When rolling it in the way it was before, once it got all the way in it was pulling up real hard on the fabric mount(camper side) because the roll was to high. Being 2" lower now, the side arms bottom out against camper right about the same time the roll meets the camper. Doesn't seem to be pulling on the fabric mount near as hard now. Even with it being 2" lower, still plenty of room at top of entry door to open and close with out rubbing. Have some pics on my phone after the mod. i'll see if I can post them.
