I put an add a leaf in the rear of my f150. It is a cheap and effective way to go. The downside is the lack of ability to adjust it. however, my truck is almost always loaded so It handles exactly as it should. It was definitely a stiff ride unloaded but if you are permanently mounting your camper there should always be enough weight to make it ride as normal. The front is a more complicated problem, though obviously that doesn't see as much weight except when you are going downhill or braking. I am running a leveling kit and stock everything up front, I am a little worried about ball joints and tie rod ends but I am 20000 miles on it with lots of off road and pot holes, so far so good.
