As suggested, TREAT TREAT TREAT and PRAISE PRAISE PRAISE! It has to be a good experience to get into the truck.

I'd also suggest that you try feeding him his dinner in the truck. It may have been that he had a difficult time in the truck last time (footing, car sickness, etc.). So get him into the truck, feed him his dinner, let him out. Then add starting the truck, then moving a few feet, then around the block, etc.

I knew of a horse that HATED trailering. Many thought he was just being stubborn. It was always a trial to get him on.

Later we learned that he was previously trailered in a rickety old trailer and the man would drive while intoxicated. The poor horse did all in his power just to stay on his feet!

So we had to teach him that trailering was actually good! Fed him his dinner in there, left it out so that he could walk around it / in it whenever he wanted. Once he got used to it, he loved it! You could just throw the lead shank over his neck and he'd lead himself! ;)

So once it isn't so scarey, he'll come around. Just be PATIENT PATIENT PATIENT!!! :D Getting mad at him will only set you back 10 steps for every one you've made forward.
