Finding the Type of Trailer that is Right for You

Horse trailer

Trailers are either straight-load (horses face straight ahead while traveling) or slant-load (horses stand at an angle). While most horses prefer to travel straight, a slant-load allows for more horses (or a larger tack/living area) to fit in the same size trailer.

“The first thing I ask a customer is, ‘What kind of horses do you have, what size are they and what are you doing with them?’ The second thing is I ask what tow vehicle they are using,” says Kevin Scott, a salesman at Nelson’s Trailer Sales & Service in Ocala, Florida, which has been in business since 1965.

“The advantage of a straight-load is that it’s better for larger horses like warmbloods and Thoroughbreds,” says Scott. “You also need to consider trailer height. Seven feet is standard and that’s fine for breeds like Quarter Horses. If you have bigger horses, you’ll want a 7’6” height. Standard trailer stall width is about 32 inches, but for a larger horse you’d want 40 inches.”

Whether you want a bumper pull or gooseneck style also depends on how many horses you’re hauling and your preferred equine activities. People who show or travel frequently often want a gooseneck with living quarters, or at least a tack room.

When it comes to materials, you have three options: aluminum, steel or a combination of steel and aluminum. The two major advantages of all-aluminum are that it never rusts and is lighter in weight than all steel trailers. For these exact reasons, an all-aluminum trailer will cost significantly more than an all-steel trailer of the same size and style.
