Mark,

While a dual foot version of a CS 144 with a dual sheave has promise, as I recall, the CS series requires inputs from the ECU. Best look into that. This was the result of an emissions issue. The extra load of the alternator made the cold engines runt too rich to stay running.

There is also a supplier that I used before the depression (and the end of my shop) that can supply just some ama$ing hardware.

Look up and maybe even call <balmar.net>. If I had spare money, I would have one of theirs and the correct regulator in my coach.

Another consideration.... Put the inverter close to the alternator. Less copper to buy and longer run of the 120V lines.

Next thought, refrigeration compressors do not need pure sine. Mine (about the same size runs just fine on a CCV 1500/750 from Hazard Fright and has for years now. One burned out on us one day, so for less than 50$us I just stopped and bought another. This on, I paid for the protection and then took the smoked one back, so now I carry a back-up that I have not needed in 8(IIRC) years. The reefer pump runs just a little hotter (~5°F on the case) on the inverter than it does on shore power. It still makes ice real fast.
