I too bought one of the Harbor Freight air compressors. I used it when I had several air leaks that ran the 110V air compressor a lot. I didn't care if a $100 unit burned out. I was pleased the performance and sound level. I looked at the mounting and it is very close to the California pumps (CP), it looks like drilling 2/4 holes could mount the HF unit. You would remove the motor/compressor from the HF unit leaving all but motor/compressor unit, then mount and wire the unit using the control system, unloader and 110 from the coach.
I have used the HF for over a year and am happy with it.
I have not replaced the CP units as both are working and I have one spare.
