After doing months of research, wearing out my friends and calling or e-mailing every dealer with-in 500 miles I am buying a new 2012 3500HD 4x4, gas auto, dually with a flat-bed already on it. Reasons: diesel too expensive to maintain and very problematic, not many around in good shape, most trucks around here are the 6.0 Ford time-bombs and are still over-priced. The truck is mainly to be used for mulch, hauling mowers and for leaves in the fall. Putting my Boss V for snow. Having a hoist installed and drop down sides. This truck is the best for our business, doesn't mean it would work for everyone. Also the DOT issues are another reason to pick a 3500 over 450.
