I wrote off a Subaru Forester pulling a Puchaz. Photos of skid marks at the

scene showed one trailer brake seized across a slab transition lining up
that
wheel behind the hitch - then let go.

The Cobra manual advises that if the combination begins to sway:

1. Hold the wheel straight and brake.

2. Do not accelerate or counter steer.

Not having read the manual at the time, I applied 2.

Towing capacity is generally predicated on a shorter distance between hitch

and trailer axle. The Europeans and Australians often use an anti sway
hitch.

The new fibreglass top trailers do tow better, especially compared to
certain
Flintstone trailers.

Make sure the rear and trailer tires are inflated to the max.

When reading the maximum pressure off the sidewall, check the age of the
tires. Replace if older than five. It will save replacing a fender after
the tire
blows.
