Have a tiltbed trailer with I love except for days like today when use it to haul skid loader moving snow. Have a hard time getting up the tilt when have snow on the tires, the wood is just a little to slick. Whats the best thing to use for a traction bar? Expanded metal or somethinhg like 1/4-1/2 inch square bars welded to the outside rail. Or would something like a baler belt work?
