I like the pin system on the car hauler even tough Dave does not
Gives you the ability to adjust the chain length for different vehicles. I always need extra chain for my 4x4 labs bumper as the chain eyelets are up under / behind the bumper.
I also like those chain bolts Dave posted. What sucks down here are my retail resources are so limited. Ordering two speciality bolts online is not cost effective and it pains me to do it. There is one trailer place in the county. See if I can get over there tomorrow.
