Hello from Cushing WI,
Just got some photos of the overcab bunk the only thing keeping it together was the aluminum skin every board was rotted and punky. Some in my family are calling me a bit wacky and I do have to admit I could very well be.
Well I got the RV for free and the lumber I have a lot of it lying around one thing I am doing is using screws 4" to hold the various pieces together and also Tite Bond 3 glue.

Ok here are the photos.
Well there you have the front
