Hi Matto,
The storage system, below, came out of a need to reduce the weight of my previous wooden box/draw setup.
Got this made to hold 4 boxes on top, 6 in the middle, and 2 long and 2 short on the bottom..
It is made in 3 parts..The fridge and lower level, the middle and top level, and the water tank/ cargo barrier behind. These all bolt to floor and each other.
I have put a couple of boxes in to show them loaded.
They are very basic and very light. The cargo barrier is part of the 75L tank. This setup is very strong, gone nearly everywhere..
