I have a 2020 29RS. Within 6 months I noticed that the wood veneer applique on the bottom stile of the sliding door between the bedroom and bath was peeling off. I contacted GD customer support about getting a new piece of the adhesive-backed veneer. After a couple of days I got a call back saying that they didn't have that as an individual part, and instead, they would send me a whole new door. Sure enough, about a week later a new door arrived. After transferring the hardware from the old door, I got the new door hung, good as new. Just wanted to pass this along in case anyone else runs into this problem. I congratulate GD for standing behind their product.
