Used drawer system from a FZJ80, will fit all 80s. Brand unknown. It's been in the shop collecting dust for a number of years so it's dirty and may need paint, at least a good cleaning. It's lined with a rhino-liner-like covering. Plan was to use this on my personal truck but never got to it. Most/all hardware is there I believe.
It has tie downs and on one side you can put your fridge.
Pics show it installed when I purchased an 80 it came from, and removed which is it's current state.
Local pickup preferred, it can go freight but that is the buyer's expense. $250 local pickup, or $300 if I have to pallet/strap it.
