looking to buy a pre-dpf 2007 t800 with the 475 c15 acert cat and a 13 speed ultrashift, 237wheel base and 3:36rears.
what mpg can i expect with this truck running midwest regional pulling a smooth-bore milk tanker 80k one way and empty back?
i heard the mpg difference is minimal to non-existant in the t800 vs t600
any things i should look out for in this truck/engine/tranny?
