Dometic Awning issue (shoulder or set screw)

Hello all,

We are new to the camping scene and recently purchased a 2010 Sunnybrook 269 THX. We went on a little three day excursion to Indian Lake and have already fallen in love with our new hobby.

We had a bit of an issue with the awning in that I realized, where the Dometic Sunchaser 8500 that is on it, the lower left bracket that bolts to the trailer was pulling away from the body of the trailer and the bolts at stripped and pulled thru. I tried to tighten them but they had stripped. The awning works fine but I knew it was a matter of time before this bracket would rip the rest of the way off. I got home and put some larger bolts in which did the trick however, I found the culprit. It seems there is a set screw or shoulder screw that the awning rails rest on when in the closed up position. There was so much tension pushing on this shoulder/set screw it was pushing the bracket that striped the screws down and out. In order to relieve this tension I had to remove the set screw. As of right now I have the set screw back in lower than where the rail wants to rest to alleviate this tension. Per the picture link I found below, it is that shoulder bolt on the lower left hand. My question is, does that rail need to be resting on that shoulder bolt or what even is its purpose? The rail wants to rest half way between one of the holes the shoulder bolt can screw into therefore, to have the rail rest on said bolt you have to push the rail up (creating tension) and add the shoulder/set screw which will then add the tension back and likely pull my new bolts out eventually. Hopefully this is enough detail friends. Thank you for any help!

    Of course it does ... the information you need is shown in that last pic you posted. 8273000.401B is the tall hardware in polar white for a Dometic 8500 ... you should find a similar model information sticker on the roller tube that will provide the exact model of awning you have, including two letters that indicate the colour of the fabric. An example.
  • I forgot the original owner said the awning was replaced in 2014 so the manuals I have a likely not correct either. I have attached some further pictures. You can see where I have the shoulder screw now, it sounds like this is OK?

    I also noticed that the rails stick out towards the top and they are flush together on the bottom, is this normal? They both do that evenly to the top so I am hoping it is designed this way.

    Lastly I found a label but it does not show me a model.

    The 8500 and Sunchaser are different series of awnings, parts for one won't fit the other ... from your pics it appears yours would be an 8500. You'd be well advised to identify exactly which model you have from the sticker on the roller tube and hardware so when it does come times to order parts for it you'll be ordering the correct parts. ;)
  • That post does align the top of the arm with the bracket when closed. If it closes properly you should be good to go. What may have happened is the previous owner let the arm fall and hit the post when lowering the awning. Previous owner of our MH did that. I can see where the post is bent down slightly and paint is chipped off around it. There are 2 rubber bumpers on the outside edge of the top bracket. When the awning is closed the upper arm should rest against these bumpers.
  • Should be OK to take the tension off by lowering the stop. The awning should latch in at the top when stowed. The purpose of the stop is to keep it the outer part from sliding down too far when the awning is extended and used in the ground leg position.. The stop also helps when the awing is being rolled, so that the roller is positioned correctly at the top.
