It is great that the authorities are taking an interest in overloaded and unsafe vehicles - I see far too many Transit / Sprinter type beavertail transporters carrying cars which I know take them well beyond their 3500kg gross weight limit
I've been stopped by VOSA/DVSA on three occasions and always found them to be very reasonable and pleasant to deal with....but maybe that's because they are always surprised to find I'm using a calibrated tachograph and following the necessary rules regarding drivers hours and trailer weights
Victorgte - I'm not too sure on the rules about homebuilt trailers, but both the tyres and hitch should have a load rating figure on them, so as long as you don't go over the lower of the two, or your cars maximum towing weight, I'd suggest you should be safe ?
