  • Awning won't fully retract at rear when hot

    It's been hot here in AZ since we got back from our long cross country trip. We have been using our awning a lot to shade the area next to the RV as we unload/clean, whatever. I noticed this prior to my trip too but it's super evident now that it's certainly heat related.

    The heat seems to expand the awning "barrel" to the point that it's too long for the channel mounts. When camping somewhere it's 75F or cooler, the awning will roll up perfectly. Camping in a hot blazing sun, the back end hangs up/binds.

    I tried checking to see if there's a way to set the depth of the "barrel shaft" into the awning arms, but I'm not finding much luck.

    Any ideas?

    It may also be possible that the fabric is misaligned or "stretching" in the heat causing this issue.

      Double check the back channels that are attached to the trailer for bowing. That issue caused mine to hang up. I posted a thread on the repair. Post a few pictures of the existing situation.

        Front tucks up good and tight. Back hangs up, but only when it's hot. And yes, those scratches on the front decals suck. I did that on some tree branches I thought I'd cleared at a gas station in Oklahoma. :(

          Just spit balling here:

          When the awning is extended, are both ends of the roller the same distance from the trailer?

          Have you checked to see if the back support arm is racked and/or bent?

          Same for the bracket mounted to the trailer?

          I'm not questioning your observation, it's just that if this is a thermal expansion problem, I would expect the awning fabric or roller or arms or brackets to expand more uniformly than on just one end. The exception would be if there was something shading part of the awning, like an adjacent tree or building.

            Awning does extend evenly on both arms, though when it's retracted, it does seem to spool somewhat unevenly. The fabric seems to inch towards the front arm as it rolls up.

            I can get it to close up if I help it out by pushing the rear arm forward as it closes up. I don't see anything bent or kinked.

            Just odd that it worked great for a month in 75ish max temps and the day we get back here to the surface of the sun, it starts hanging up again.

              The fabric inching forward on retracting is either the seam not riding evenly on top of itself, or the awning fabric is not square. Think of it as rolling up a rug on sleeping pad, seems like they never roll up even because one end gets ahead of the other. If there is no problems with the arms or the roller itself, I'm thinking the fabric managed to stretch unevenly or slipped in the track.

                I think you have your answer. The frame has tweaked slightly from your tree branch impact. It does not take much. Closely inspect the outer channel for any deformations or binding/bends and where it is occurring. If you cant tell get a yellow crayon and rub it on the inside edges of the outer channel and run it closed. It should leave a mark where it is binding up. Chalk will work too.

                These units don't like being out of adjustment at all. A slight racking will cause the issue you have. If you find any pinch points, carefully expand the outer channel or compress the inner depending on which is out of alignment. I would use one of those trigger clamps that can expand, but if you have strong hands that should work too, I used a block of wood and door shims to wedge my outer channel slightly more open.

                  I should have mentioned, this problem pre-dates the branches. Apologies for the lack of clarity there.

                    My point is there is interference in the closing. You have a bent/warped channel somewhere that prevents things cumming together. Extend everything and use a good straight edge along all the arms and back channel. Inspect the joints and pins. Make sure the locking collars on the pins are fully seated. Are all the backing brace screws fully seated? Otherwise invite a bunch of friends over, do BBQ and have everyone watch closely. Somewhere there is a bow , dimple, or bulge that causes the channels not to line up correctly.

                    Is there a way for you to post a video of the situation?

                      RV is sleeping under its cover until our next outing, which is TBD date but I'll grab a video next time and post it up. Of course, by then it'll probably be reasonable temps here in AZ... Thanks for the assist!
