My brother n law and partnered on a trailer a few months ago. I have never had my car on a trailer so the question is what is the best way to secure it to the trailer? I've have seen using 2 fixed length chain/cable to secure to the front of the trailer and 2 rachet tie downs at the rear. Or, using 4 rachet tie downs at all 4 corners. Give me your experience and suggestions. Thanks.
