In fact at a Taupo test day last year, I did go round having a look at trailers, not to check on WOF's etc, but to get some ideas, as I was about to build a 'homemade'. I was amazed to discover that a good few of them did not have either WOF or Rego and a couple of them had come over from Napier!!!! Beowulf, you will remember that day.
