So - we changed our PVC to Motor Caravan on the V5C but just spoken with DVLA as vehicle category is N1 and they say this doesnt change. Dartford Crossing use the vehicle category to charge which is a whole pound difference to what Bessie used to cost. Not a major issue as we very rarely use the crossing but just curious to know what Vehicle Category other PVCs or for that matter any other type of Motorhomes have on the V5C.
