Hey all - recently went camping, therefore it rained everyday. Got to thinking that Slide Out covers would be a nice addition. I have a 2018 29BH Fifth wheel. Has anyone added covers to the slide out? Did the OEM add a reenforment strip behind the wall panel to attach the fabric? Being an light frame I know its a laminated wall....fiberglass, stroyfoam and a thin wood venneer on the inside. Hoping they added something to attach these to. Anyone know?
