he trailer has a steel skin, so it can be easily drilled. I'm sorry, but I don't know what a Hoss organizer is. I had a Corn Pro and modified my tack room area by adding various fittings for the hanging and storage of tack. One of the best items we purchased was a tack trunk that had a handle on one end, and wheels on the other. Show equipment was kept in there, keeping it clean and readily available. Hanging equipment on the walls, keeps the floor area open and lessens the chance of breakage. The sky is the limit as to how you could fit the inside with cabinets and storage. You're only limited by space and imagination.

Do yourself (and your wallet) a big favor, and don't order from the company that markets HOSS.  Instead, search online for discount gridwall displays.  I bought mine from http://discountshelving.com/ if I remember right... it was a long time ago.  Same exact stuff, with one exception... saddle racks.  You have to buy those from the HOSS people, I think.
