Thanks for your comments. Again, nice to know someone else had problems
with this setup and it's not just that I don't know what the *$&% I'm doing.

===================================

What you want is something known as a "backing solenoid" which is
activated by your back up lights. The solenoid activates a valve
which relieves hydraulic pressure and allows backing under any
circumstance. My Load-Rite trailer works this way, and it also has a
pin that you can insert into the coupling mechanism to keep it from
sliding just in case the solenoid is not working for some reason.
