Honest Comparison

How It Compares With the Alternatives

Fixed side wall trailer	Side board/drop trailers offer greater cargo versatility for over-height or irregularly shaped loads
Two-axle trailer	Three axles provide higher payload capacity and improved weight distribution
Airbag suspension	Mechanical suspension is lower cost and simpler to maintain, but airbag offers a smoother ride

Use Guide
