How much stuff would I be able to fit in this tack trunk? Is it too small?

I have that exact trunk and I fit all of those things in there, plus shampoo/mane & tail conditioner, fly mask, fly spray, gloves, & another pair of muck boots! So definitely this trunk will work! I am talking from experience here!! & I wouldn't go with a saddle rack. I had one of those before I got my trunk and I always found that things were getting stolen/used without my permission... :\
