FWIW:
I noticed right at the start of the thread that someone mentioned using a van, but the allowed weights are pretty useless, most are 2 tonnes max, so you're better off with a Disco or similar. We have a pair of Renault Trafic LWB DCi 140 and 150, and a Master 2.8 turbo before that, and they are only 2 tonnes max trailer weight.
