Domestic power relays have never been reliable, that's what is activated when you use the Domestic Power Switch. Generally, the switches never fail, HOWEVER.....
#1. Do yourself a BIG favor and simply bypass the relay which will eliminate never having to get caught at the worse possible time for a complete failure to happen. Losing all 12 volt power to your coach in the middle of the night during a rain storm is not pleasant.
#2. Purchase two 12 volt PowerPulse units for your batteries. Install one on your house battery bank and the other will be installed on your chassis battery(s). It will eliminate any sufation from forming onto your new battery plates extending the life of the batteries.
#3. Always use distilled water and keep the plates covered at ALL times.
