On another note, my V5 shows a Mass In Service of 1960Kg, this presumably is due to the fact that it was originally a T28 panel van, now that's well below the threshold for a Dual Purpose Vehicle even before fuel and driver weights are accounted for, but should this be changed to reflect the added weight of the three seats in the back now it's been converted to a Kombi? (even though I can't see a way of doing this on the V5)?
