Just found out that my MH has MAM 3650Kg stated on the V5C but it‘s taxation class is private light goods. My understanding is that if it’s over 3500kg it should be PHGV and thus lower VED. Just been on to DVLA and the person I spoke to said that I require to get a Weighbridge ticket to demonstrate that the vehicle is indeed over the 3500kg and send off V5C with covering letter requesting change of taxation class. Anyone had the same problem? Would appreciate any response that may possibly clear up my confusion regarding this ‘grey’ area.
