Due to our current horse situation (one riding horse, two miniatures) we've done some looking around and we're pretty sure we want to go with a stock trailer with a large center divider making two box stalls. The minis would go right under dividers in slant or straight load trailers (unless we did a lot of modifying), and my husband wants the space for using the trailer for other things - picking up lumber, atvs/snowmobiles, helping people move etc.
Almost all the trailers I've found have been 6'6" tall. That seems a little short, but they're obviously intended for horses - quite a few of them have tack rooms with saddle racks and bridle hooks. Last I checked cattle, pigs and sheep don't need tack rooms.
If we hold out long enough I suppose we might find a good 7' tall one, but honestly there are some nice looking (and nicely priced) trailers that I hesitate to pass up on.
My current mare is a shortie and is only 14.2, but we're hoping to get my husband a horse eventually and that one will most likely be in the 15 but not more than 16 hh range. (Originally he wanted a Clyde cross... I think he's changed his mind, as a green rider a shorter horse means a shorter fall!)
Anyone else out there with a smallish-to-mid-size horse with a 6'6" trailer? Do you like it/regret it?
