I think soft side campers have very specific uses that make them ideal for people in those situations. If you are expecting to go off road on roads that 4x4 is required, then a soft sided camper with it's lower height, lighter weight and lower center of gravity are strong advantages.
On the other hand, if your intention is more highway traveling, staying in improved campgrounds, state / national parks and RV parks, a hard sided camper will have it's advantages of less setup time, better sound and heat insulation, more storage and more space overall.
In my opinion, the type of truck you are looking at purchasing tells me you are going for the latter scenario and not the former. I agree with the others, if your going to purchase as much truck as you are looking at and carrying a large hard side camper, go with the dually for peace of mind. It isn't necessary but if your concerned about crosswinds, it's extra insurance exactly where you want it.
