When I registered my imported Frankia at the Glasgow DVLA office they put my MGW down as 5300kg but it is only plated at 5000kg,it can be uprated to the former which I'am considering doing.The question is,do I need to? If stopped what do the authorities go by,is it the plated weight or what is on the V5? I checked what it says on the DVLA website via @icantremember link yesterday and it shows the revenue weight,which is 4110kg.This is what Frankia claim it weighs leaving the factory but with all the extras it weighs quite a bit more than that as I took it to a weighbridge last week.Someone else posted a link to a company that sells blank plates that you can enter the details on,would this be acceptable or would I need to prove with supporting paperwork that it had been been officially uprated if stopped ?
