Exposed External Metal Trunking. Easily Touchable.

Do you think that the trunking is earthed, or will it just contain S.W.A. cables and not be earthed, as likely the supply is P.M.E?

Could be either.

The regs. seem not to prefer large outdoor metal conducting masses connected to a P.M.E. supply, such as caravans and steel hulled boats etc.

Caravans/boats (and electric cars) are perhaps special-ish cases in that we'd expect people to regularly grab hold of them and perhaps in less than ideal conditions (wet or no footwear etc). There's little aversion to PME with other equally large or larger metallic structures - e.g. lamp posts or the outside of steel framed & clad buildings or even steel bridges.
