This is a farm converted HGV lorry drag trailer with good aluminium floor. It is on air bag suspension and air brakes. Built in sept 1997 according to the data plate and rated at 14 tons, axles are 7000kg rated.
Whether it complies with the modern road regs I have no idea, we have only used it on farm but the lights work and brakes do too. If you wanted to tramp up and down the roads with it you would need to service it and check out the legality of a farmer conversion! It does ride very well on air suspension. Built in jack leg.
Open to sensible offers, we just sold our tractor with air so that is a bit of a snag for continued use for us!
