The ARB compressor mounting bracket is not my favourite design, I understand why it is built like that, but it is very tedious to remove where I have placed it.
So I fixed it to a piece of 5mm sheet with some countersunk screws.
And installed some nurserts so I can fix from underneath
Tidied up the wiring
Put a divider in the storage bin
With some holes for air to pass.

An ally grill will feed air from the tray space
This will keep the water out when no tonneau.
Iíve been thinking about a small lawnmower type air filter behind the grill, but wonít overcomplicate it just yet
