I personally like the stock combo trailers. The BO at my place has one made by Cimarron, its a big 4 horse trailer, but can fit 5 horses if they are smaller, its got the dividers turning it into a slant load, and its got the goose neck tack room in the front. I love it, its big and airy, which is great for Southern California. I like having the option of being able to leave a horse free in the trailer, and with it being a stock trailer, its very open lets a lot of light in, and isn't as "scary" as some of the fully enclosed trailers out there. I would say go for it.
