You might want to look at the popup line of campers by Palomino. There are some that will work with a half ton. There is also "4 Wheel Campers" that will even go on a Ranger or Tacoma, but you pay for the lack of weight. I have a half ton and ended up putting Timbrens on my rear suspension because my camper puts me right at my capacity, but that is before I get in the truck, my wife the dog, and the camping supplies. With the added help of the Timbrens the truck rides beautifully, but I know I'm still riding heavy. I may add helper springs before I'm done.
