Default Tow Hitch Ball - 50mm or 2"?

Howdy John (aka Mr. Tyrebiter),

Mudhead in Marfa here. As you might recall, I towed my Blanik (L-23)
trailer back and forth from Miami to Marfa several roundtrips until I
settled here. I used a 1 /7/8 ball and the trailer stayed on. I also
drive relatively slowly (55-60 mph), even on a long 2,000 mile journey.
I get there when I get there, and without the fatique of a stressful
fast pace. Sometimes it's best to avoid the Interstate routes with
those 75 mph big trucks blowing you around.

In any case, you should stick with the 1 7/8, or buy a 50mm ball from
www.HitchCorner.com They have a terrifc website about hitches,
grease, etc. They are located in Littleton (near Denver) Colorado,
USA.

I can also tell you that a 2 inch glider trailer hitch WILL jump off a
1 7/8 ball going over railroad tracks. Chains did their job - no
damage - no breakaway.

One of the most important trailering tips (besides "slow down") is to
alway put the pin or bolt through the safety latch on the glider
trailer hitch. Some folks skip this for a short drive and later regret
it when the latch moves aft and pops off the ball.

Ask me someday how I (and my Dad) learned all this stuff (pre- r.a.s.)
! It's a bit scary but we never put a dent in the gliders - just the
trailers.

I needed to move a Blanik L23 trailer over the weekend. Using my 2"
tow hitch ball and I had a heck of a time disconnecting the two. I
knew that the Blanik trailer has what I assume is a 50mm tongue.

I was kind of surprised that my 2" ball (which works out to be 50.8mm)
would be a problem disconnecting. 8/10's of a millimeter difference
doesn't seem like enough to worry about.

What is the tolerance on a 2" setup? Is it so close that 0.8mm can be
a problem?
