Hi Doug,
I thought you might notice your old trailer. I just had fun with restoring it. It is better than new - I reworked the wiring harness and it's tucked away without interfering with anything. The special dolly I built helps alot with storage and moving around.
I've been autocrossing for many years and at this point don't "plan" on upgrading - if anything, older would be my choice (but newer is definately better).
