Always good to see photos for ideas ...

Recent photo here at J30.us shows Crusader's trailer in New Orleans for the NA.

Looks like it uses doubled 3/4 plywood shaped as done on a cradle, and bolted onto steel supports, instead of the typical adjustable screw pad arangement.

For a long haul I like that support.
