OK, so I'm new truck shopping. They don't seem to sell manual transmission 4.3L V6 half ton 4wd W/Ts for a cheap price anymore, so I might as well buy a truck I like. And cars... while they get good gas mileage they aren't much good for anything but transportation appliances. So, I'm sitting there playing with GM BuyPower figuring stuff out. Basically pricing a 2500HD and a 3500 with: standard cab long box W/T 496 and 6 speed manual Snow plow prep package Trailering package Cruise control blah blah blah The only difference between the two when I built them was the price. Roughly $2,000 different. The trailer ratings seemed to be nearly identical. model curbweight/gvw 2500HD 5400/9200 3500 5700/9900 So... what makes the 3500 worth two grand more?
