I refuse to believe that my mortality is in the hands of Tom, his car and dolly, his RV, and 700lbs over the hitch rating. Seems to me that Tom will probably be a little extra careful and aware due to this limiting factor. I see WAY more dangerous things daily on the roads.
There won't be an LEO anywhere that would be able to "eye" 700lbs over, come on. Let's try and be real.....
I wouldn't think twice about only 700lbs. It won't be a "danger" thing in this instance, more of a long term stress issue. If 700lbs snaps the hitch, it was bad from the beginning.
