I have a Bison-three horse slant load. It is an older model. Good trailer. I have used all type of trailers. In the end it comes down to the horse. I usually trailer mine alone. The horse is 15 hand, 12 year quarter horse gleding. No big issues. When my horse is alone there is enought room for him to turn around an come out of the trailer head first. I usually discourgage this. We usually have a discussion. He present his points; he is 1,200 pounds, has for legs and really does not want to back out into what he cannot see. I counter that I have more intelligence (will sometimes), I have had to put down horses (tearfully and unfortunately) and unless he wants to walk his fanny back some 25 miles to the barn he will do things my way. Sometimes this actually works.
