Thinking about buying this Kenworth W900, what you guys think of this deal

Favored,i have a mech.cat,about 5.6mpg's is as good as your probably gona get,imo. Is it a b or c model? How long has it been since the rod-bearings have been put in?

 

See if you can find out the block serial no. too.

 

hauling a cow wagon you are looking at well over $1/mi just for fuel for that truck. mechanical cat is about as good as it gets other then that. it's not like a computer motor though. turning it up will only decrease your fuel mileage.

All of our mechanical cats in 379 petes 13 or 18 speeds, 3.33's and pulling 48 foot spread axle reefers got 4 to 4.5mpg on average running west coast.

 

To me keeping good records is always a great idea, the owner can periodically check to see if it's about time to replace certain things and how well certain parts and brands are holding up, and when you want to sell it's a great way to show the prospective buyer that its been taken care of. You will get many opinions as to which truck to buy, but you will stay busy on the computer and burn a lot of gas looking at trucks that won't have what this truck has to offer, along with the records which you won't find to often. I love my B model for several reasons, they're tough as nails, easy to work on, and can deliver a bunch of power with fairly cheap and simple mods. You didn't say where the owner lives so I don't know the terrain, but my truck will get as bad as 4 1/2 mpg with 80000 lbs in the mountains, and as good as 6 1/2 mpg in the flats or with lighter loads, so I tell people that I get about 5 1/2 mpg average, but with a bull wagon you will probably going to lose 1/2 mpg no matter what engine you run. I think from what you've told us, the truck would be a good buy, if you need another truck. The retail parts price would make it part out for about that price, ie. 3406 B running in good shape about $6500, trans about $1500, air ride cut-off about $2500, then you still have cab and misc. parts including wheels,tires,radiator,exhaust,bumper, etc. I hope this helps and good luck with whatever you decide.
