2019 GMC 3500HD Options

Since your 3500 is a dually it will be rated to carry the weight of that camper with no problems. The snow plow prep package usually includes higher rate front springs, which may actually be helpful with the camper. I just bought a 2019 F350 and it came equipped with both the snow plow package and the camper package (and a fifth wheel hitch prep package, and a gooseneck hitch prep package, and pretty much every other prep package they could throw on it). So the snow plow package and camper package are not mutually exclusive, at least not with Ford. Finding a truck with both sure is hard to do though. I looked through hundreds of trucks in on-line inventory, and only found two or three trucks that had both packages.
