OK, so a proper fit between the hitch and ball is important, too.
What do I do with
my Cobra trailer that fits a 50mm ball? I actually *do* have a 50mm
ball but it has a
1" shank. However, my car has a 1.25" hitch receiver (factory
installed), and I can't
find any fittings that will take a 1" shank. For the moment I'm just
using a 1 7/8"
ball (47.6mm) since the trailer just goes from the tiedown to the end
of the runway,
and I've heard the horror stories of using a 2" ball (50.8mm). Any
ideas that don't
cost an arm and a leg (such as "buy a new car")?
