Theres no reason you won't get 6 mpg if you are grossing 80,000 or less. At 660k it could last to a million or it could go tommorrow so I'd lowball him as much as possible. On the bright side the 3406C is probably the best mechanical engine out there. I had a 88 K-W T600 with a 425 CAT/8LL/4.11 on short rubber doing tandem flatbed work. It ran 1700@65mph and got 7 mpg on flat ground and 6.5 in hilly terrain. Grossing 137,000lbs it got 6. Good luck.

That's interesting, and not the first time I've heard it either but when I ran mine at about 1600 a while back I got 4mpg. Haven't done it since. 3406B 400hp 18sp 3.90 rears.

My mechanic also said the C motor was the best. By the time they built the C they had all the bugs worked out.

If I had the $ I'd buy that Pete. My '96 FLD has same setup except my trans is .73 overdrive. I get over 8.2 mpg deadheading @ 60 mph or down in the 4s running 90 mph uphill, grossed out into a 30 mph headwind!

MPG is mostly driver, load, terrain, weather, then truck.

Buy it! You don't wanna drive one of them ugly slanty-eyed trucks everyday do you? Gaaaaaaaakkkkk!

My FLD has less miles, and more new stuff on it and I'd sell it for $15K cash. Come to Indiana and get it!!!

The truck your looking at is a rip...... I can get you a 05+ Columbia with mid 300K TOTAL miles for about $12-$15K
