pretty much what the others said is what I have seen.
I've been all over georgia, lousiana, alabama, miss, some of texas, in a 1 or 1.5 ton f350 / 450 with a gooseneck and my personal tractor .. never been stopped or challanged.. never went thru a scale.
I have plenty of straps and tie downs. nad plenty of truck.
A few years ago i finally gave up white knuckle hauling on a 1/2 or even a 3/4 ton. got tired of thinking.. well.. it's only 1 trip. or a short haul.. etc.
bit the bullet and got plenty more enging, barakes, frame and rubber under me.
feels safer.. is safer..e tc..
didn't break the bank either.. my 7.3psd's are used and older 99's
