Being a crane operator the first thing I noticed was the lack of outriggers on the truck. Something that big hanging off the side of the truck would make the truck tilt or even upset. But then again there could be some kind of side support I don't see?
Trick photopraphy, look how far out into the road the hogs butt is sitting, then re-evaluate. Big pig but not huge, and not wild. Too much hair, no rub marks or scars, and his toes are too long. Wild pigs travel, and wear them things down.
