Class A restore bad idea

I have a 1984 Turbojet Airstream 30ft RV we bought in 1994, and have since replaced the Isuzu diesel engine and transmission. Now the new engine has 50,500. miles (100,000 old Isuzu engine)on it plus radiator rebuilt 3+ years ago with very little miles as also front tires, and the RV remains stored indoors. All of the coach items work from refrigerator to even new electric items, you know alternator, converter to all batteries. Can you tell I have done all those repairs? I am thinking this Airstream really would not be considered such a restoration project and would be ripe for sale. My concern: Does the aluminum skin require replacing rivets as a stage of restoration. Also, I was once told by acquaintance RV dealer that the aluminum itself would be of great value to bring even $10,000.? Would that be true? I appreciate any insights for me to proceed.

P.S. I couldn't seem to list the information on my RV correctly for my RV profile. None of the years would take?
