There's probably no practical reason to get the V5 updated, other than avoiding the possibility of some officious git using the mismatch between van and V5 as an excuse to pull you over, fine you or otherwise grind your gears.For fear of being pelted with Tomatos! I've been reading this thread and the linked thread from @Salty Spuds above. I have a T6.1 (T30 Highline if anyone is wondering!!). It had a full professional Camper Version 3 years ago by Dormobile (were Bristol Campers). It's Black, has dark tinted Windows all round, a pop-top, 6 travel seats including the driver (the rear 3-seater converts into a bed) and Barn Doors that also have the dark tinted Windows installed. The V5 was never changed and is still stating as the Body Type: Panel Van.
This question is purely for my own clarity, I have not been caught speeding {touch wood}, I'm aware of the law and speed limits for vans and that DVLA will probably tell me to sod off for attempting to reclassify my Camper as a Motor Caravan. All the conversations here (especially from those "caught") mention a Body Type of "Van/Windows". So my question is "is it worth me fannying about with the DVLA to get my V5 Body Type changed to "Van/Windows"?
Given the current state of affairs with UK officialdom, though, the chances of that happening would appear to be vanishingly small.
Just be careful how you describe your van to your insurer. Supplying your VRN plus a full list of mods should cover your arse in this regard.
