My only problem is getting the horse to load. Most trailers look like an endless tunnel to most horses, that one is more so. See if you can test drive it with a horse in it. I'm not sure if the wheel placement would make it more stable or less so with horses moving about in it.
The price is right that's for sure
Are there duel wheels on the front and back? I just worry about it fish tailing with that axle placement
ETA if your only going to haul one horse, no matter where you place him front or back. I think your going to get fish tailing. If he's in the front he's to far behind the front axle if he's in the rear its too much weight on the rear. My physics may be way off on this but that's the way it seems to me. I would definitely want to try it out with a horse in it.
