Larry, I too have experienced issue with the Carefree Awning on my 379. Unfortunately, mine was more severe, and had to be replaced due to what I firmly believe is a defect/failure in the awning's ability to auto dump. Long story short, on a camping trip, had some rain, which I'm guessing accumulated on the portion of the awning above the dining room slide (which is another discussion point). Per the manual, awning was set at it's highest setting for "auto dump". In other words, it was set to it's flattest setting, vice, it's steepest setting. Heard a loud noise, went outside and the front awning arm had totally elbowed, and I mean BAD. Awning fabric was pinned hard against the top corner of the slide and I feared it was gonna tear through. Called my brother in law to bring in some ladders. Over the next 3 hours while I waited for him, I tortured myself staing at a god awful mess. I was sick to my stomach. Once he got there, we were able to *carefully* retract it, and get home. It was especially demoralizing, as it was our 3rd outing in our brand spanking new dream camper. My dealer and Grand Design split the cost of the replacement, and warrantied it - thank goodness. Initially, GD took the stance of "storm damage", but through the help of my dealer escalating the matter, I got a full replacement, minus the fabric, which surprisingly was still intact, and rebounded nicely.
I've dealt with Carefree in the past on other campers, and will tell you they are "socks on a rooster" - totally worthless, in my opinion. Good luck if you decide to get resolution from them. I can only speak from my experience, and to be fair, maybe others have had a better one.
I know this may be spitting in the wind, but I'd love to see the data on issues with the Carefree awning. I can only hope, GD takes this into consideration, as they have what I feel is a solid, quality product and company. Given that, who they surround themselves with to produce their product, BETTER be of the same caliber. In the case of Carefree, I think they are coming up short.
Not trying to be a hater here....just saying..
