I have a medium sized Stanley I take to day or overnight shows/clinics. For multi day shows, I use my large tack trunk.
I have the Husky tack trunk and I love it! I can usually take it to shows easily but if you're looking to store a lot of things make sure you get the appropriate size for your needs. It can get a little cramped inside, but so far it has worked well.
We have 2 Husky and 1 Stanley (we have 2 horses )
They are the large ones, have a removable tray, have wheels and a large handle to pull them with. They are easy to put into the trailer to take to shows. They come with keys to lock them. Also, if it rains they do not leak.
