I have had our Burstner uprated by J R Consultancy to 3850 from 3500kg. I have the new VIN plate and design weigh certificate along with a letter stating that it has been done by a"Suitably Qualified Person". If I send the V5 away for updating it wont be back in time for our trip to Germany in a couple of weeks time. I could apply for a Temporary Registration document but this does not show any weights (I had one last year when I had lost the original V5). I'm thinking that I should keep the current V5 for the trip and produce the accompanying paperwork as proof of new weight and send off the V5 on our return. Do you think this is the better option especially as I will have to send off the new design weight certificate as well?
