Glad this thread was started. This is my current project. I have been deliberating over which system/design to use myself for the last few months. Do I leave the seats in? Should it be easily removed in minutes or semi permanent? Water tank? Looked at all on this forum and each had their good points, some very good designs, but none which satisfied all my wants. Looked at many on the web and also contacted a few custom fab companies for design suitability and pricing. Custom Installations (WA) and Full Boar Fourbie (Vic) do some really nice work.
I'm after a permanent drawer half filled with recovery gear and tools etc., the other half on trips filled with camping goodies. A heavy duty fridge slide with a footprint just wide enough to allow for my fridge, and a cover for stacking gear on top on trips, but removable for access to fridge around town without opening tailgate and sliding out. Space for my solar panel and Drifta kitchen. Water tank.
I have decided to make my own.
Due to several factors, mainly the size of my 90lt NL fridge and also that I wanted the extra 17mm in height required at the rear to allow clearance of the tailgate, to be built in to the drawer system sides and not just a spacer at the rear edge. I will be using 12mm & 17mm marine ply, mainly for noise absorption and 6mm ally plate. It will stay in the car 99% of the time, but able to be reverted back to original without much fuss.
Seats will be removed. It's nice to know you have that seating capacity, but I have only used those seats once anyway. Removing them will save some weight and allow space for spares, infrequent used tools, inverter, water pump and a larger capacity water tank.
I wanted a water tank behind the second row seats, but even with 900mm deep drawers, the off the shelf ones wouldn't fit.
With the fridge being so big, I need to use full extension 914mm sliders (these ones 227kg Locking Drawer Slide - Heavy Duty ) so when extended it will clear the upper tailgate panel mould and allow full opening. 864mm won't allow this. That makes for a total drawer length of 942mm. This doesn't leave much behind the rear seats. With the angle of the seats I would get a small tank of about 30lt; but with removing the seats, I can use that space below the false floor on each side of the centre seat support which will stay and help support the floor. Should end up with around 50-70lt.
The other thing I really wanted was a pull out table built in to the fridge slide. Unfortunately the height of standard ones are between 110-130mm, which once again didn't allow the fridge to open. After many trial setups with the fridge and using bits and pieces to replicate the fridge slide angle and final height, I will use 6mm aluminium for this part which will allow a slide out table and full opening of fridge.
The fixed drawer side will have a slide out top to allow access to the removed seat space below the floor. Something like this;

Not everyone's cup of tea, but I think it ticks all my boxes. I'll post up a few picks in a month or so of the finished product.
