The ramp is 2x3/4” light wall square tubing. Holds up yamaha venture fully loaded with the nro gear.
750 lbs easy.
And its light. They add glides for the carbides and fasten cleats for the track.
Skis clear the deck,some need a riser on the gate for longtracks to slide ramp in/out.
I'm using two by one medium wall for most of it and I have two eight Footers for the ramp and some light wall 2 by 2 angle iron left over from the dovetail and cut into 4 foot pieces for cross pieces.
I'm assuming having it up on Edge would make it stronger than laying it flat underneath the plywood for the ramp?
