Hi everyone, great forum, lot's of information. I have a 1998 f150 supercab with the 4.6L, 8.8 axle and 4x4 and would like to know what max payload can be put on the Bed. I checked the GVWR in that door and it says 6000 lbs. then i checked my truck registration and it mentions net weight of 4300 pounds so I would assume 1700 would be the layload... I am looking at a truck camper of about 1600 pounds and that would be the average i see out there plus or minus 100 pounds or so... Dry weight. If I go over the GVWR by about 300 or so pounds would that be an issue? I am planning to add helper leaf springs to the back to help control the load. Anything else I should do? I would like to stay under the GVWr but it's hard to find a truck camper with what i need below that rating including myself, gear... Please help..... do I need to get HD kleaf springs, axle tires..... Thank you
