Hi Bought my B544 about a year ago. The DVLA registration is for 3500kg but there is a certificate and an external plate uprating to 3850kg by SV Tech, which would be private heavy goods. The road tax is less if I register as PHG but I would need a medical certificate to keep my heavier class licence soon really not at all sure what to choose. I will go to a weighbridge to check the current weight to see what our max extra payload is, I will never be towing anything. Any thoughts on anything else I should consider?
