Fair enough on the curtain airbags – but I’m going for it being (arguably) safer to have passengers separated from 4 bikes and a mountain of kit by a rigid bulkhead vs no bulkhead and curtain airbags 🙂
In the old Dispatch Combi there were mounting points in the roof and floor for a guard / bulkhead so I made my own fairly tidy steel grille (best of both worlds) but the new shape Dispatch / Spacetourer does not have the mountings – presumably because of the risk of an aftermarket bulkhead interfering with the curtain bags.
The DVLA thing is totally illogical but unfortunately the truth. Car derived van is on there, as is Motor Caravan. MPV was listed as body type for our old M1 combi, but they just won’t include DPV (even though it is a term with legal definition in Construction and Use regs.) To quote one of my replies from DVLA:-
“blah blah blah the V5C Registration Certificate does not have a requirement to show if a vehicle is Dual Purpose and, therefore, is not something that would be displayed or added”.
And from DVSA where I’ve got a work contact who is fairly senior:-
“I don’t think there is any way of demonstrating what the vehicle is by any official means, it’s just a case of the vehicle meeting the definition”
So I’m pretty happy I’ve got the paperwork to fight a ticket if I ever have to.
From an informal chat with my contact, I think the Government hates the existence of Dual Purpose Vehicle as people use it as a VAT / company car tax loophole, so they make it as difficult as possible to document and define.
