$6.50
Strengths: (working/break)
Rathceting Load Binder with chain 6600/26400
Ratchet straps with chains on the end 3000/10000
Normal 2" ratchet straps 3300/10000
3/8" chain 6600/26400
axle straps 3300/10000
Using the binders and the axle straps the weak link would be the straps, but 4 could be used - 2 on each axle to nearly double the strength. I'm not sure what happens when one comes to as smashing stop from 50+ mph with 4000 lbs strapped to the trailer...
Thought?
