What to check before buying

  • Search the frame and welds at the axle mounts — that is where cracks start.
  • Check the brakes and the last inspection in the papers.
  • Work the gross weight against the towing vehicle before buying.
  • Compare the chassis number with the papers.
  • Look at the floor, cover or body from the inside — rust does not show from outside.
