You will no doubt have guessed that I have a caravan and take it out of a weekend and holidays, to cause frustration to other drivers who cannot pass and so get stuck in a huge tailback ??? Don't believe it !! If you ever get stuck behind me, please write and let me know, because I'm usually the one overtaking.
My good friend Gopher dubbed my caravan a 'Tenko Box' because he compared it to the metal incarceration box used by the Japanese during WW2, and in his eyes there isn't much difference. Well there is !!! My Tenko Box has a shower AND Gopher's little hatchback won't be passing me (sorry Gopher).
As a consequence, some years ago, I acquired the nickname 'Tenko'
