Anyone familiar with Nextrail. They no longer make horse trailers. It looks like an American version of the Brenderup but possibly without the engineering behind B'up. Customer is looking at one and I don't have any opinion on it. It's an 8 yr old trailer. Wonder if parts are generic or if we'd have to fabricate them if needed? Is it all aluminum, seller says it is, or is it a composite of some sort? It has 2200 axles but is warmblood size. Has the inertia brake system. Anybody with an experience please chim in.
