New emissions regs for diesel

Hi,

I'm very confused about these new regs for diesel vehicles - there seem to be lots of info about cars, but what about larger vehicles like motorhomes? It all seems very depressing - we'll soon not be able to go far in France, or may not even be able to keep our motorhome on our own drive. Should we just sell it as quickly as possible? How much trouble are we going to get in if we don't have a Crit'Air sticker? Was really looking forward to going to Normandy in May, but now we don't know how much red tape and issues there are going to be with our 51 plate motorhome!
