With another beautiful day in paradise, we continued our quest to dewinterize the motorhome.  After reinstalling the drain plug on the hot water heater and filling the freshwater tank with chlorinated water, the lines and tank were evacuated to remove antifreeze—the pump worked and no leaks!  Since it had been a couple of months since the motorhome had been exercised, we opted to to kill two birds at once by exercising the motorhome and in doing so, allowing the chlorinated water to slosh around in the tank killing any bacteria and mold that might have developed over the winter.  Regrettably, the chassis battery was dead, forcing us to use the coach batteries for backup starting.  Driving did recharge the chassis battery, but some sulfate probably collected on the plates, so to maintain its longevity, it’s being desulfated.  While driving, we noted the driver’s side brake light and turn signal was not working, so we made that repair as well.  We also exercised the on-board generator.  After about 4 hours, the water tank was drained, fresh water was added, and faucets opened to evacuate the heavily chlorinated water.  (The latest issue of the Family Motor Coach Association magazine has a really good article on the whole process of dewinterization.)  Now, it time to pack for the RVing season.
