hitching up the trailer. This means moving the tongue weight from the ball to directly over the rear axle. I've had good success with this adjustment procedure, and if you think about it, that's exactly how a truck is designed to carry it's load.
I'm talking about a truck here, and not a minivan, or a sedan, or a sports car, or any other goofy thing some people decide to tow with.
I suggest you check your vehicle's owner's manual.
OOPS, I stand corrected....completely missed the header line. I can live with this recommendation....although I think it is incomplete. BUT, and I don't know if you all know this, but automotive Owner Manuals MUST be written at a 6th grade reading level! Kind of hard to make complicated technical issues clear at a 6th grade reading level. One of my first assignments in 1984 as a new hire was to write Buick Owner Manuals. A very frustrating experience. I was always told to simplify sentence structure and use little words!
(A) Body to Ground Distance (B) Front of Vehicle
When using a weight-distributing hitch, the hitch must be adjusted so the distance (A) remains the same both before and after coupling the trailer to the tow vehicle.
If you use a step-bumper hitch, the bumper could be damaged in sharp turns. Make sure there is ample room when turning to avoid contact between the trailer and the bumper.
If you will be pulling a trailer that, when loaded, will weigh more than 5,000 lbs (2 270 kg) be sure to use a properly mounted weight-distributing hitch and sway control of the proper size. This equipment is very important for proper vehicle loading and good handling when driving. Always use a sway control if the trailer will weigh more than these limits. You can ask a hitch dealer about sway controls.
