Made some progress: Took down the cabinet/enclosure, disassembled it.
Got the heavy load shelf placed, leveled and confirmed the car's position. I've got a foot or two of margin, that's fine.
finished the framing, I think I will have a cabinet for my compressor, too, will help cut down on the noise (a little). Test fit some of my totes, good fit. This shelf is supported by the floor so heavy objects can go here.
