I've got a 2002 Ford F450 that was a highway construction truck. It has a knapheide flatbed with an integrated hitch. Looks very sturdy. I want to bring some black topsoil back from the midwest this year for raised beds. I will be hauling a 20ft car carrier with construction tools, riding mower and atv in it. I can't find any reliable specks on the bed and tow capacity. Please any advice on figuring my load weight and tow capacity. I was plannning on putting the dirt in the bed with sidewalls and want to fill it up if possible. Thanks!

 

The hitch should be attached to the frame. If it's only part of the bed, contact Knapheide and ask them.

For the truck rating, you can go to fleet.ford.com and scroll down to owners manuals and download the manual for your F450 that will give you the truck GVW / GVRW
