I've got the Goliath which is the larger version. Love it and it gives the ponies a great ride.
Indespension don't make horse trailers any more, but they do make many other sorts of trailers on the same base with the same suspension so replacement parts are easy to come by.
Thank you all for your replies. The general verdict seems to be that they are very good. Now I have actually seen one I must agree. But, how on earth do you put a value on a trailer that is not made anymore?
