New truck for me what to do

[Tcwkjv]

So I am buying a 86 F350 manual 2x4. Truck has a 1990 7.3 IDI. It is running good and everything but as it is new to me I was gonna change all the fluids from top to bottom to start a fresh. Yall have any more recommendations for what to check or re do on it. Says 86,000 miles unknown if that is in new engine or if it’s rolled over a time or two.
One issue the guy said is if the truck sits for a couple weeks it’ll pull air off the front fuel tank.

Water wetter in the coolant is a good place to start.
If the edge of the brake pedal is worn down to metal, it probably rolled over.
if the drivers seat edge is worn out, it probably rolled over.
if the drivers door sags, it probably rolled over.
So you tell me, HAS it rolled over?

Change your filters too. I know you'll change the oil filter, but change the fuel and air filters too. Of course check over your belts and hoses too. Change those if anything looks suspect.
