We have a 2001 9100 IH daycab with a ISM in it and it gets the job done day in and day out.  paid 17500 for it 3 years ago with 425k miles and its got a 10spd in it.  Honestly its a very easy to drive truck and it for the most part its a comfortable truck.  Plenty of power unless you want to pull 120k up a mountain.  No its not flashy it doesn't have an nat approved motor or tranny but its paid for and to me that's more important.  I wouldn't have made a different decision given the chance but I do like the looks of a 379 ext hood Pete just not the price for what you get.  It's a farm truck.  You are not making a living out of driving it.  

Nothing against guy that have the nice flashy Pete's at all and yes I am a little jealous.
