A lot of people are leery about trials... Here's what I would do: Go try out the horse. When you test ride, don't overdo it. If you get on and right away don't like him, be polite about it but say you don't think it will be a good match. If you do like him, don't ride for an hour. You should be able to tell pretty quickly if you feel like it could work out. Afterwards, try to make a decision. If you think you need to try him again, do so. If you decide you want him, I would suggest using a vet out there. I wouldn't ask if they'll bring the horse up to your vet- not without paying them adequately anyway, and even then I know I personally wouldn't do that. If you can be there for the vetting, that would be good. You could bring your trailer up with you, meet the vet, get the exam, and as long as the vet sees nothing wrong take him home with you then. If you want to ask about a trial, do it before the vetting though. Most owners will take a horse back if it turns out to be a bad match, but of course there are also plenty who don't want to take back a sold horse. I can't say I always agree with that, but if you buy the horse it's yours. Don't buy it unless you're sure. Also, if you could get a friend to go up with you (maybe for the second ride, should you like him and be interested) that would be better. I think it's helpful getting another opinion so you don't overlook any major issues and end up with a horse that isn't suited for you. Hope this helps, and good luck!
