If you have a Dometic (A&E) 9100 series awning on your RV you may wish to save this post. Last season I started having intermittent issues with our awning not wanting to extend. It would roll out about 6 inches and while the motor kept running, the awning fabric began to unroll in a baggy mess, the arm would not move anymore. I'd have to pull out on the vertical arm and then it would finish extending properly. Back then I just thought it was a lubrication problem and after oiling every moving part, it seemed to be better. The problem came back with a vengeance this season. This time lubricating did nothing. Rooting around the web it seemed the consensus was my gas struts had lost strength. Being they were 5 years old now, I figured that was possible so I ordered and installed new. No help. Wasted my money, the old ones were still perfectly good. Talking to the techs at a local RV shop they insisted the awning was just "worn out" and needed replacing ($1000+ !!!). Called Winnebago and several agents there had no clue but gave me Dometic's hard to get customer service number (800)366-3842. It took 3 agents there but one finally knew of a "bumper kit" for sluggish awnings. Found it online ($50!!) but the only review there was a complaint that it came with zero instructions and the purchaser had no idea how to install it or how it worked and the seller was no help to him, either. The part = 3310777.000 bumper assist kit. Looking at the picture, it seemed to me that all it was just some sort of rubber thing that would push the vertical arm away from the coach when you went to extend the awning. I happened to have some of a dollar store pool noodle left over from making corner guards for the slides so It occurred to me that it might do the job. The noodle was 2 1/4" in diameter and I cut a 2" slice and placed it between the vertical and upper arm. It tucks down in there nicely and seems pretty well trapped in it's location. I did this on each side and, voila! Problem solved! My only concern is whether the noodle will get too compressed and no longer push out on the arm. Time will tell. I may have to devise some sort of spring arrangement.
Dougrainer explained it very well I also went to the Dometic website and they had pictures of it but no instructions It does have to be positioned just right For it to work properly I will try to get some pictures for you where it is installed Instead of using a rivet are use the self tapping screw instead it was easier My arms were already installed on the motorhome So the self tapping screw was easier
The Dometic Part has a hole in the round part. The round rubber tube you install at the torque point of the awning arms on the awning arm tube mounted to the RV sidewall. You drill the 3/16 hole thru the Arm into the wall, insert rubber silicone and install the rivet THRU that hole in the rubber tube and there is enough compression to allow the rivet gun to expand the rivet. This does what the OP did with those green foam tubes. If I remember, Dometic sent the kits out at No Charge when under warranty and they did NOT have any install directions. I had to call Dometic when I did my first one. If I also remember, when installed and the awning is retracted, the bottom of the arms pooch out about 1/4 to 3/8 inch. Doug
I had the same awning installed at camping world what a mess Brand new out-of-the-box it did the same thing they thought the arms were bent they change them and here it was just a bumper assist that I had to figure out They also didn’t know nothing about the kit or how to even install it I did buy it after medic for $50 and it does work It’s a shame they should just install it when it’s new are ready Should come with the awning
