Cracked water heater not a common problem. Of all issues we have experienced over the years, a water heater failure was not one of them.I do flush regularly. Frig coil failure pretty common, last few years, particularly if installed in a slide-out. Already replaced one in our 2015 dometic frig. Proper heat venting and leveling critical. Wiring mistake sounds like a headspace problem with the installer. WH/Frig are vendor products common in all makes of RVs. I would not blame on your unit being a Mountaineer.
