speedy

Great transmission, but for short trips, even a 6 speed will suffice. Gears are great for hills or soft ground. But if you don't have to overcome those conditions, it's overkill. Great thing about a 12 speed is that you get 5 gears in reverse, of course, the six speed gets you that too. The Mack 9 speed is fine too. Do you have experience with shifting transmissions with multiple gears? It's an acquired skill that you may not get fully polished on short trips.

Well, I guess it sucks for you. Buying and selling in private deals, or even on a dealer's lot is a crap shoot sometimes. Real Estate is especially that way - or used to be....

First one with cash on the dash that's acceptable. Unless somebody is willing to put down a forfeitable deposit (or at least a portion of it) to hold it for a couple days Paypal, Credit Card, Western Union transfer to me....

That's going to look real good with that sleeper. Lots of work, but it's going to be a unique piece, for sure!! I'm looking forward to more pictures.

Sounds like a fuel pump problem. How's the fuel filters? Collapsed fuel line?

It's so odd to see a sleeper on a DM, with the offset cab. Thanks for sharing.

The 427 was a hell of an engine. By comparison, most 460's are a dissapointment, at least, that's been mu experience. But getting the proper software for the hardware won't hurt. (may not help much, either)

Nothing wrong there, his rig has 24 wheels.

The 'Trolly' brake lever (We call it the trailer brake or 'spike'), should NEVER be used as a parking brake. It can work it's way off by vibration of the engine or even simply ease off on it's own. It is not to be relied on for parking - use the buttons on the dash. That being said, it's main use is for braking in slippery conditions, it will help keep a tractor-trailer straight - you can also apply the pedal brake and override it to apply even more braking pressure to the trailer - this takes some experience/practice. It can also be used to back under a low trailer that doesn't have spring brakes, back up to the trailer, connect your air lines, pull the spike to apply the trailer brakes and then drive the truck under while the 5th wheel lifts the trailer.

I'm not sure what the costs would be, but if you have some mechanical inclination and basic tools, it's easily a DIY job.

It's likely that you have a cracked oil cooler. Replace (kinda tough to repair, but it may be possible) it and flush the engine and radiator

A badly out of round tire? Are the wheels unimount or daytons? Could be they are wobbling too. If you suspect balance, maybe rotate the outside tires 1/3 - 1/2 of a turn (or thereabouts) one at a time and test drive in between. Would axle alignment have anything to do with this?

You can add a 'Blixxton' module to it. 3 minute install. Adds power and fuel mileage in most applications. http://www.bigmacktrucks.com/index.php?showtopic=4286

I couldn't tell, was that a load of Sailboat Fuel, or Dispatcher Brains?
