Build steps
Cut the three stringers from 2x6 ground-contact boards, with a plumb cut at both ends at the slope, from the cutting diagram.
Lay the stringers on edge on the ground, 36 in apart outside to outside, and square the frame.
Screw the 2x6 decking across the stringers, flat, 1.5 in apart, from the low end up. Two screws per plank per stringer.
Screw a 2x4 side board on edge to each outer stringer face to keep pigs from stepping off.
Rest the top on the truck bed or trailer floor, and chock or chain it.
Before you start
A 15° ramp (24 in over 90 in) is the steepest a pig will climb. For a 30 in tailgate, build the ramp 2 ft longer.
The gaps give grip and let mud fall through. For piglets, add a 1x2 cleat every 8 in.
Walls stop the pig from stepping off. Keep it dry: wet boards are slick.
