Well got the Kobalt setup in the smallest bay and it is a perfect fit with room for the 50ft hose, accessories and plenty of breathing room for the AC.
Tested and drained tank 3 times, and checked tire pressure guage and air pressure cleaner. I'll try the tires in the next couple of days, have to remove TPMS to fill the tires. Once a year is no problem. I may just change the batteries at the same time. I run 100 psi, and a couple tires are in the 90-95 range.
Glad I went with the rubber hose, flexible and rolls up nice, fits compactly in the bay.
First impression is, I like it. See how it does in the long run. Only downside I see is the drain valve knob is a plastic L, it has a screw, so it can be replaced when it breaks., and the regulator control knob is plastic, but it seems to be a solid plastic.
The unit cuts off as 155 psi, forgot to check the guage to see when it kicks in. It seems to fill and refill quickly.
