rfj, you talked me into getting a new cargobox designed before to long.
Coming up this weekend Wayne and I will be working on adding the Blue Sea fusebox and 2x12v outlets in the back to power the fridge.
Also after much thinking, I am going to have a carpenter here at work who is on my crew build me a new cargobox.
I really dig mine, but I want to turn the fridge 90 degrees, and the present Engel tray will not work with the cargobox as it is not deep enough, that is why it is mounted sideways.
He runs a cabinet shop on the side, so it will be killer.
It will not be any taller, just deeper and a little wider to take advantage of the FJs layout since it was built for my '91 4Runner.
I will then mount the other type of Engel tray, the one that lets you slide the fridge out.
This way I will be able to open up the lid all the way.
