The Cross Country 3903BT is a 39-foot tridem live bottom trailer and one of the highest-capacity three-axle belts in the lineup. Its body sits two feet further forward than previous designs, adding payload and lowering the centre of gravity for a more stable ride. Hardox 450 wall liner, moisture-resistant wall insulation and a 4-inch pitch roller chain make it a low-maintenance, high-cycle paving asset.
