That chain would have to be 3/8'',not 5/16'' looking at the size of those binders.I am a big proponent of diagonal cross chaining,much safer all around.The thing I don't care for here is the long slow angle of the chains in the rear.The geometry is all wrong if there were stresses being created during an oopsy that might release the rig from the trailer.For sure with all that slack,those binders would have to be constantly re-adjusted.I hate moving those genie lifts,especially when I'm all by myself as your vision is limited.I'll get off and on the seat 10 times at least to make sure I'm all squared up nice.
