Don, that may be too much camper for your truck. It sure is squatted. That camper requires a Class IV truck, which is a 4500. That's according to my RV Consumer Group Guide.
My 11' 3" Lance also required a Class IV truck, but it didn't squat near that much. Camper has no slide outs. Picture taken in Alaska in 06. The jacks were down only to stabilize the camper when moving about inside, however I would never try to pick up the truck and camper with them. The camper is suppose to weigh 4500 lbs wet, but I believe we were much heavier with the way my wife packed it for a two month trip to Alaska. The bed on my truck has a payload of 4750 lbs+/-.
