My camper, bought used, came with shocks for the front. They went from roughly the front of the camper to the front front fender, just in front of the joint by the door. They didn't work for me, on my crewcab. Very simply, the upper bed overhang was not long enough. With those shocks in place, mounted where they were supposed to be at both ends, I could not open the front doors. I thought that was pretty inconvenient. They were never mounted to the truck.
This camper will affect the handling of the truck. There is no way around that. I had mine originally on an F-250, single rear wheel. The word 'squirrley' comes to mind. There were times it was downright scary. It caught a lot of wind, both front and sides. I put Helwig 2500 overload springs on the truck, and that helped some. That same camper is now on my F-350 dually, with no overload springs. The handling is much improved, though the frontal area still kills any idea of decent mileage.
So, plan on a fairly slow trip. Feel out how the truck reacts to the camper. And remember, that camper weights a bunch. Your braking effort will suffer accordingly. Be sure the brakes are in top condition. I weighed mine once, and it crossed the scales at 10,200 pounds, truck and camper. There were some things in the camper, but it certainly was not loaded for camping. Add in half fuel and me as driver.
With care and common sense, you can enjoy that camper for a long time.
