New O/O, Old truck what do I need to keep her in top shape?

Aluminum bodies still corroded and were a PIA to fix.

To the OP, I would either rebuild the fifth wheel or replace it altogether.

 

you mention the cabs rotting, I already planned on removing the seat and rubber flooring to deep clean it. While I’m in there is their a good rust preventative you could recommend?

 

POR-15

 

Oh hell yeah! Gunna clean the hell out of it and lay down some of that por 15

 

Ditto on POR 15.

 

Get the complete kit, actually, better yet, call them and ask them how much you are going to need; you may need the gallon of cleaner and prep each and maybe a few gallons of the sealer. I think $300 should be right to do it right.

 

Win or loose its all on you , all i can say is Good Luck !

 

Anybody know why the previous owner would take off the pyrometer at the exhaust and plug it with a pipe plug like the one show in this picture

 

A threaded plug to plug the hole . Idk why they discontinued it , too lazy to replace pyro ?

 

Or did they move it to the manifold to get pre-turbo readings?
