I searched for some on HorseTrailerWorld
My favorite, it looks really nice
Decent stock trailer
Nice looking goosneck with back tackroom, stock combo, mats should be replaced.
Aluminum gooseneck stock combo trailer, 4 horse, its a straight load but doesn't look like there is any dividers between the two horses standing side by side so you could use the middle divider that seperates the front and back horses to make two big box stalls..
Good luck! Just click on my text describing each trailer, it should bring you right to the ad.
