Just finished and installed my drawer system, couldn't justify a $1000+ for a branded system. These are just on 300 mm high with 260mm drawers which allow me to have my bottle Jack and my compressor standing up. One long, one short drawer to allow my waeco 35 litre fridge to sit in front of the short drawer and the different widths to allow access to the spare wheel winder in the floor pan. All up I spent $135 on timber, ply, screws, latches and glue. The carpet is two different colours, scraps from other projects. Drawers slide relatively easy, used the yellow tongue plastic that you see in ply tongue and groove flooring, 4m length at Bunnings is just under $5.
