I, too, started hauling horses and cattle in the 1960's. And unlike Wildfire, I have seen 6 accidents involving death of horses, cattle, dogs, and humans. And have friends and family involved in another dozen. About 1/2 were because of being overloaded. I have watch a couple hundred horse trailers dangerously sway when in high wind, the live cargo moved or passed by an 18 wheeler.
I don't know if this "trumps" his experience, but my mileage hauling animals is well over 500,000 miles. Some in big rigs, most in pick-ups. And I recommend enough truck and a gooseneck with living quarters.
