Hi Jad, thanks for an excellent and very timely thread. I have a 2017 MUX and have been looking for weeks trying to find a temporary solution for securing a portable fridge and 2nd battery in the cargo area, without having to take out the third row of seats! Unfortunately Im not skilled like you to make this deck, and probably need to find someone close to where I live (Dunsborough), perhaps a cabinet maker or handyman etc? I too am thinking of putting a slider in, but see you have taken it out? Do you possibly have the dimensions of the deck and recent photos of it in the back of your mux? I assume it is about 900mm long and that would determine the size of the fridge + battery box that would fit on one side? I need to get both of these items and have a sparky fit them properly. Many thanks for any advice.
