I posted on this once before and now realize I gave bad info

. I got mine close, but never right. I had passed on some info to "PanJH" regarding adjustment and he passed back some info I didn't know. Today, I finally found what the various adjustments do.
I think the biggest issue most have, if you have one, is that the awning doesn't close tight and seat against the box. Mine didn't and rattled when I closed the door. I'm sure it was rattling on rough roads too.
I did the following adjustments by setting up a ladder and using the awning remote to bring the awning in and out while working on it.
To start, here is a photo of pretty much everything you need to adjust.
First - In the upper left of the photo is a red band. It has two holes marked with a + sign and arrow. These use an allen wrench, but it's actually easier to get a long flat nose screwdriver with an 1/8" blade. The hole closest to the coach is to adjust the tension when the awning retracts. This is probably the one that most need to adjust. An 1/8th of a turn in the "+" direction (clockwise) will make a pretty dramatic increase in the pressure that is used to pull the awning closed and the cover into the box. To tight and it will put too much pressure on the box. It's pretty easy to get it just right.
The outer hole is to adjust how far out the awning goes. If too loose, the awning won't extend properly and if too tight, the awning will over extend and make the material flop over. This adjustment probably doesn't need to be touched. This adjustment is only on one end.
Second - On some coaches the awning hangs to low and the arms and even the outer facia may get hung up in the last inch or so when closing. To lift the arms so the facia and especially the arms close properly there is another allen adjustment.
Looking at the photo about upper center, you can see where the arm attaches and pivots. There are two allen screws there. One controls the tension on the spring and probably doesn't need adjustment. About an inch to the left is a second allen. This one adjusts the arm/awning height. There is one on each side.
If you turn this one clockwise, the arm will lift. Make this adjustment on both sides so the arms enter the box without hitting on the bottom. Lifting the arm slightly makes it easier to adjust the allen screw.
Third - The plastic cover on the end of the awning, what I'm calling the facia may be either too far forward or too far back and doesn't seat properly when the awning closes. This was an issue with mine. To move the facia either forward or back there is an adjustment in the bottom of the photo. It's the two allen screws just to the left of the spring. These two allen screws, when loosened, allow the whole arm assembly and awning material to shift one way or the other. You can look at the roller and see if itls too far forward or too far back.
Loosen the two allens, lifting lightly on the arms allows them to loosen more easily. If your facia is a 1/4" too far forward, slide this mount a 1/4" toward the rear of the coach and retighten the allen screws. Go to the front arm and do the same thing sliding it back a 1/4". Make sure you retighten them.
Once is everything is adjusted, run the awning in and out a couple of times to get the material to center on the roller.
It looks like the awning hangs on a rain gutter and then is secured with two 3/8" screws that you can see inside the box when the awning is open. I checked these and found they both took a full turn. They could have been loosened by the awning being out of adjustment and vibrating/rattling in the wind.
I hope this helps those who want to take this adjustment on.
