Yes, the black drawers on the left side.
The fridgeslide is made with HD slides ...
So far it worked very well. The underside is carpeted as well, so it slides very easy; even fully loaded.
No latches. Tailgate keeps them closed; -)
I'm located in Germany ... bought it on amazon:
it's 30x30mm
The two black drawers on the left have no slides. This is just a tight fit. They are guided by aluminium rails on the bottom, on the top and on the two sides. To make them slide more easy the underside of the drawers is carpeted as well.
For the fridge slide i moved the side rails 5cm (2 inch)...
I have built a similar drawer system for my Discovery 4 with two drawers and a fridge slide based on the same extruded aluminium in 30x30 mm.
It's easy to work with and seems to be very sturdy so far.
