My first two trucks where built autos, the last two where manuals with dual disk clutches, one a nv4500 and the other a nv5600.
IMO a stick gets boring to drive. It is nothing like driving a stick in a fast car or anything like that. I went with an auto because simply, if I pull up next to a mustang, camaro, ricer, powerstroke, whatever, I dont have to worry about slammin gears to put an ass whoopin on anyone.
Chris at ED once told me "Built Autos are where its at, manuals belong in sports cars" or something along those lines haha
