So I finally got around to building my steel tray a couple of weeks ago. There are a lot of similarities to the just powder coating tray a few guys are running as they look the goods! I went with the 300mm high C sections in 4mm running parallel to the chassis and used the same 6 mounting points as the tub. All bracing is 3mm angle in either 50x50 or 30x30. The outer frame work and headboard is all 2mm RHS. I had the pull out drawer and side tool boxes fabricated at MW Toolbox which were pretty good quality and price. I spray painted it myself but being winter in WA at the moment probably wasn't the best idea but I can always touch it later when it heats up. In the end its going to get banged around out bush so not bothered.
I will say the car drives so much better with the extra weight over the rear heavy duty springs so happy with that. I still have to fab up the rear roll bar for a throw on canopy which ill do later
