Just wondering what I gotta do so I can hold a 8.5FT Camper on my 96 F150 longbox with a 300 six. Any input would be very helpful.

 

Hmm - before we answer, it might be best to know how much the camper weighs all loaded up, what your GVWR is, and what your truck weighs without the thing in there. You may be biting off more than you should chew, never mind that it's longer than the bed. Seems to me most of those things were built for 3/4 ton trucks.
