Re: [RC] Response to unstable trailer. - Sisu West Ranch

If you brake the tow vehicle, the trailer will come around as you found out. If you do anything but attempt to go quite straight, the whipping of the trailer back and forth will most likely get worse.

Speeding up the tow vehicle will tend to stabilize things. Applying ONLY the trailer brakes will tend to stabilize things. Brake controllers have a lever or slide that will manually apply ONLY the trailer brakes.

No matter what you do it will be quite scary, and unless you work very HARD TO DO NOTHING TO EXCESS, the adrenaline will cause you to overcontrol and make things worse.

It is much like driving a rig on ice. You have to experience it to get the feel of what to do. If one is lucky and lives in an area where there are large lakes that freeze over in the winter then you have miles of glare ice, with no obstructions (or ice fishermen), deliberate skids can be practiced until the skill is learned.

The stability of a towed load depends on a bunch of things. How much weight on the hitch of a trailer is important. Weight in excess on the back is worse than more weight on the hitch. (the rule of thumb is 10% of the total weight on the hitch.) Tires on the tow vehicle. I presently have two different brands on the Green Machine. If I switch the front tires to the rear things become unstable. (I am going to match things up before the next trip.) With a bumper pull, load distributing torsion bars can make a real difference, if installed, adjusted properly, and used.
