All LocknLoad platforms can be used on the top level of the EasyRider trailer, but size J is the best. It fills the upper level nicely and will not have issues interfering with the towing vehicle during sharp turns.
On the lower level, sizes E and K are recommended. We don’t recommend using larger platforms on the lower level due to the fixed crossbar position biasing the platform too far forward or backward on the trailer, possibly causing issues with clearance during cornering and would also interfere with Tent Kit installation.
3 pairs of LocknLoad Crossbars Clamps per bar are required to get maximum clamping force to the trailer bars and frame.
