Outer Limits 4x4 Board

I have a Prado 120 v6 and would like to fit a storage unit possibly a single draw and a fridge slide on the left hand side.
I was wondering if there are any second hand units or what would you recommend if I was to buy new.

I've got an Offroad Systems Storage unit and I love it. They were able to build me exactly what i wanted. http://www.offroadsystems.com.au" onclick="window.open(this.href);return false;
