Back to Dod's repairs. I wrote two paragraphs describing how I removed the damaged siding and straightened out the cab over section. I couldn't re-read my post and make much sense of it so I will not expose volunteer readers to that type of torture. Suffice it to say that 8 hours of work and about $100. of supplies took care of the damage. A picture may be worth a thousand words but I failed to take any "before" pictures. Here are a couple of during and after pix.

Below is the 1" thick marine plywood that replaced the damaged area.
