I'm toying with the idea of buying a truck camper for my 04 kc titan. I've been doing some reading and the payload sucks on the titans and there's probably very few campers that will work. If I can find a 1000-1200lb camper then add gear and people I'll be a bit over the maximum. What should I get to make it work? Add a leaf? Newer shocks and which ones? Also I know the rear axles are weak on these trucks will it cause stress to the axle? Or just can the idea.
