Gooseneck and 5th wheel trailers inherently tow much better than a bumper pull of the same size. Large bumper pull trailers pull like crap, and they will push the truck around. If I had to pull a heavy camper, and had a choice between the two, I wouldn't even consider the bumper pull.
A large gooseneck/5th trailer will pull better than a small bumper pull.
Think of it this way... If you are going to pull a 8,000 lb trailer with your f-150, than you should have 20% of the trailer's weight on the truck. That's 1600 lbs.
1600 lbs is a bit much for the toungue of the truck (even with a W/D hitch), but its nothing for the bed. Bed hitches also put the weight in front of the rear axle, so it helps hold the front of the truck down during heavy braking and manuvering.
People think that just because you have a F-150, you don't need a bed hitch. But getting that weight on the front tires helps the smaller trucks more than the bigger ones.
Your rear suspension will probably not be the limiting factor when pulling a 5th or gooseneck. You'll probably be too heavy to stop way before you bottom out the suspension. haha
FYI.. The gooseneck hitches in my F150 and my F350 are welded to the frame... Not bolted to the body.
