Yes sir looks like you can now receive PM's. As Tim was saying, if I can paraphrase, each of your emerging issues are kind of different. They probably belong in the appropriate form. I realize you are a new member and we are just suggesting how Stovebolt prefers to separate issues, Like one at a time.
The Panels 'N Burbs area here is a basic place for Panel and suburban specific talk. The panels and suburban's are mostly the same as trucks except for the seats and the body behind the doors. The doors and forward; and the basic frame, are the same as truck. Same parts. The gas tank is different.
Many of your questions are best served in all the other appropriate forms where truck owners/experts can answer any of them.
Looking forward to trying to help as you delineate the issues separately. So post away!
