Hi I'm Wayne,
I will help you with this,
Good Morning,
In my opinion, it is a very good built Truck,
Average fuel light to med Load 6.8 to 7.0 MPG
Normal heavy load 44-45K 5.8 to 6.2 MPG
Best shift range is 1550 to 1650
NOW the big question, how was it maintained
Oil filters change on a schedule, Greased on time,
Valve adjustment at 150K miles
was clutch replaced ,
any and all Oil samples
These are all questions you need to ask
300K, that is getting a little high, rebuild time on a good maintenance engine
600K to 750K miles
