Richard, thanks for the recommendations. I am sitting here in Modesto, CA, waiting for six air springs to be delivered to a friends home. I went ahead and ordered the MS2812 and RC-50 on Saturday so they would arrive on Tuesday, and hopefully installed before the springs arrive. As to the BMK, two years ago I installed a Zantex LinkLITE/PRO monitoring system. It is separate from the inverter and, among other information, gives me the percent of charge which is helpful. Since it and the shunt are already wired and in place, i see no benefit from buying the BMK. If you think I made a mistake ordering the RC-50 instead of the ARC, I can return it to Amazon and get the ARC. I really appreciate the offer to help program the unit. While I was in a hurry Saturday to get the inverter delivered, I found the best price at Amazon with free shipping.
