Gen2 LWB Packing System and Fridge Slide
Posted: Tue Jun 16, 2009 11:54 am
This is a repost of a project I did in early 2008
The original intention was to create a packing system that would add a second floor to the back of the Pajero on which I would install a fridge slide, and under which I would have space for 4 wolfpacks. My reasoning behind this was that I wanted the fridge as high up as practically possible. Even though this makes getting INTO the fridge a little more difficult (the Pajero does have a nice step on the bumper though) you can't pack anything on top of the fridge so there's a lot of wasted space. The flat floor gets round the wheel arch space problem as well. In addition I wanted the fridge slide to be relatively easily removable as it would often get in the way if I want to move something fairly big.
I wanted to fit 4 wolfpacks, but unfortunately they won't fit, so instead I settled on a combination of 2 wolfpacks and 2 gommoboxes. These will be supported by a single slide with tie-downs to allow some flexibility should my requirements change. I also didn't want drawers as such as swambo prefers to pack boxes in the house and we just load them when packed.
I discussed my design with various 4x4 accessory places like Safari Centre, LA Sport, 4X4MW etc, and the quotes varied from R6900 to R8700, all for systems which never really suited my requirements.
Although many people build their packing systems out of wood, or steel, I opted for aluminium because I wanted to keep things as light as possible. In addition Maizey Plastics produce "Connect-It" connectors, which I thought I could use instead of welding things together. Some people do express reservations regarding the strength of it, but I thought it would work considering some of the commercial offerings use them as well. Disclaimer: - I am NOT an engineer, and time will tell on the merits of this choice (and any other design choices I made).
The Pajero has 4 heavy duty tie downs in the back and I thought I'd exploit the 10mm bolt-holes into which the tie-downs are mounted. I hate drilling new holes into vehicles and this arrangement suits me fine.
The picture below is of the basic frame, checking for fit before I started putting it all together.
The frame is now complete, and the rails installed. The two little "arms" are the supports for the wooden covers to neaten everything up. The bottom left (in the picture) "subframe" is where the fridge slide will be bolted onto (you can see the holes for the 10mm bolts).
The frame inside the Pajero. You can see an additional frame on the left hand side. This is to support the flooring which goes over the wheel arches. The idea is that the wooden flooring covering these is removable so you can tuck small things out of the way. I had intended to mount the compressor inside the gap, between the wheel arch and the door but my Max Air compressor is too big.
OK, just some detailed shots. Below is how the Maizey Connect-Its work. The bit that slides into the aluminium has a small hole. The idea is you whack a punch into the aluminium where the hole is. The resulting "dent" hold the connectors in place. I didn't like that idea for the verticals so drilled straight through the connectors and used 8mm bolts instead.
This is the Connect-It brace piece.
The shot below shows the bracket for bolting the whole shebang to the floor of the Pajero.
And this is now where I'm at. The completed frame from the back, together with both the side pieces. You'll notice i added some braces to add some lateral stiffness.
I have cut all the materials for the fridge slide and the draw itself. I had intended to bolt all that together, but I enlisted the help of someone at UCT to weld that up for me (so will cost me a couple of bottles of my best Pinot Noir)
So ..... more to follow soon.
