The MAN TGS is the UK’s market leader in ‘Pet Regs’ tractor units. These are trucks that meet the European ‘ADR’ regulations (‘Accord Dangereux Routier’). As a result there are always plenty of used Pet Regs MAN TGS tractor units for sale at Truckpages. In addition to the fact that the TGS makes an excellent lightweight tractor unit, MAN gained a foothold in market leadership in this petroleum segment through their acquisition of ERF trucks and their dealer network in 2000. ERF were dominant in this market segment at the time.
