Great Idea Buck!
The best place (at least around here) to find one of those cushioned mounts
is Tractor Supply.
I know there are similar farm related co-op type stores all over most of the
USA.
Usually beat the Hell out of UHaul and specialty towing / RV stores on
price, too.

There is a company that makes a rubber cushioned ball mount. This
prevents
the clunking and jerking that your are experiencing. Do a search on hitch
accessories and you should be able to find the product.

My wife and I would eventually like to get a boat which would
inevitably involve trailering. The problem with this scheme happens
to be our dog. A few months ago, we pulled a trailer (with decent
loading at the hitch) with our SUV and Reese hitch (square socket
receiver). When there were bumps or speed changes, the clunks just
drove our dog wild who was in the back of the SUV. We'd like to
prevent that kind of trauma again if we were to pull a trailer. Does
anyone have any tips as to how to prevent the clunking? I'm not sure
if the clunking was primarily coming from the receiver hitch or the
ball/trailer connection, but since we had good loading on the ball,
I'm guessing it was the receiver. Anyone else had the clunking
problem? Any solutions? (I was thinking about using some sort of
shims in the receiver, but I'm not sure that would work if we were to
drive several hundred miles...) Thanks!

ps. NOT bringing the dog is certainly one solution, but unacceptable
at this time...
