There used to be a dealer in the midwest, I want to say the first name of the guy was Dave.
Anyway, they were (for years) the absolute best price on new trucks. I remember several people from the diesel forums flying out and driving back.
For the extra $1,200 bucks, get a SRW 1 ton. That was what I intended on getting, ended up with training wheels on the back.
The 3500 (SRW) will give you another 900 lbs carrying weight on a manual truck.
