Hey Roy!
Yes, the GE Appliances RV AC Control Board - Single Zone # GE27FR will work with the older 410A refrigerant style RARMC2A, but only when used with the GE Adapter Harness - Low Pro R-410A AC to R32 Main Control # GE68RR. This adapts the newer controller to the older style units.
Let me know if you need anything else!
Out of curiosity, what kind of camping do you do? Any off-grid stuff? We have some folks that have ways of running AC units off-grid, but it's pretty difficult to have that type of power supply.
