My work truck is a 2016 Silverado HD3500 quad cab, 4wd, long box, dually. It is three years old and time for replacement. I've been seeing the new trucks on the road/at job sites, and researching the specs on the net--haven't hit the dealers yet, but I need to start. My truck is HUGE, but the new ones are even bigger than mine, and the 2020 Silverado HD's are getting even bigger. Pretty soon you're going to need a CDL to pilot one. When is this madness going to stop? As it is, my current truck is difficult to park in most conventional parking lots and has the turning radius of a small city block.
