We just got our trailer back last night from having it converted from a 4 horse slant to be able to haul minis. I can haul 7 with storage in the front and the back tack still there. If I put stuff out of the front part into the living quarters I can haul one or two more horses. We are really happy with the job that he did on the trailer. Can't wait till show season again. We bought this trailer right before Nationals. Got it for the living quarters so we don't have to stay in motels. We love it. Used it to go to Nationals, but had no dividers. Luckily the horses are fairly well behaved and had no problem going to Tulsa, but I wanted dividers.
The dividers are all made of aluminum. The metal loops on the ends are for straps to hook behind them. I don't have them yet. Each divider has a pin that drops down in to a hole in the floor of the trailer.
