When I started I bought a 1991 ford with it's 1991 tanker body on it, I was the 3rd owner and the truck came from new jersey. The 2nd owner I Know used salt. The frame of the truck rusted in two in 2001 and I move it to another truck. I still use it as a spare today. My septic pump truck tank is at least 32 year old and I pumped 4 tank with it yesterday.

There is some kind of device that can test the thickness of the tank but I don't know it name.
