5th wheel question

I'm trying to find out what's going to be the best route to get my truck set up for towing a 5th wheel RV. Currently it's running a leaf flip kit on the rear with helper towing air bags. Is there a 5th wheel hitch that can give me the clearance I need for the trailer or will I need to redo the suspension? I don't know anything about lowering the suspension I've been doing some research but it's a bit hard with an iPhone, I just got this truck a few weeks ago and am still trying to get it back on the road again. Any help and advice would be greatly appreciated

the truck looks nice and low but you shouldnt have much of a problem towing a camper with the helper bags.....my dually has a flip kit and helpers and i can tow anything i need to....my truck has rails in the bed with a spyder gooseneck hitch so its alittle higher than a standard underbed gooseneck.....the 5th wheel hitches sit up even higher....most campers/goosenecks have alittle adjust built into them for differant height trucks also

thanks for the info and pictures, that gives me a good idea of where to start looking.
