We had an electrical problem earlier this spring that cost $$$ to diagnose and fix. Even though an EMS would not have been useful to prevent that problem, my husband, who loves gadgets, decided to install the Progressive hardwire EMS, I guess on the principle that electrical problems can be hard to track down and expensive to repair.
We do frequently use nearby conservation areas and parks where the maintenance is a bit questionable.
He found the installation pretty straightforward. There was room on the electrical panel for the wiring. He put the control box in the bottom of the sink unit and ran the cable for the display up the side of the slide.
So we have our modest little 211-S TrailLite with the hardwired EMS, macerator pump, backup camera. Oh, and he still has to install the trip computer. No inverter, however.
