FORD 2005 F-550 v.2 - Manual (Page 169)

Hitches
Do not use hitches that clamp onto the vehicle’s bumper or attach to the
axle. You must distribute the load in your trailer so that 10%–15% for
conventional towing or 15%-25% fifth-wheel towing of the total weight of
the trailer is on the tongue.
Integrated hitch rating
The standard integrated hitch has two ratings depending on mode of
operation:
• Weight carrying - requires a draw bar and hitch ball. The draw bar
supports all the vertical tongue load of the trailer.
• Weight distributing - requires an aftermarket weight distributing
system which includes draw bar, hitch ball, spring bars and snap-up
brackets. The vertical tongue load of the trailer is distributed between
the truck and the trailer by this system.
