>:(Extend your boondocking, and main house batteries, by adding a auxiliary battery. Most parashoots have a reserve shoot in case the first one fails to get you safely where you want to be .I had scary trip with my PC ,I got myself in the middle of a Ostrich farm in Tennessee the owner gave me permission to stay there ground was hard seamed other rv's were parked there at one time. It was a picture perfect spot, horses ,and other farm animals , came right up to the camper the owner said stay as long as you like he was going on a trip and would be gone for a while. We had everything we needed,except there was no cellular service, for miles . That night a storm came over with heavy rain. The PC stayed nice and dry, the scary thing was the ground got soft and muddy looking at house batteries showed depleted the slide was out to booth. Some thing was wrong there was no way the batteries could be depleted, but even the inverter was showing depleted voltage how can we drive with the slide out and I needed to get on a harder surface. Checking the batteries directly from outside of the coach with a voltage meter showed normal voltage .The battery gauges in the coach were reading false. The slide went in with power . The PC got us to the hard surface road .,and on we went.
Now this may not happen again, but for peace of mind I installed an auxiliary battery completely separate from the outside batteries by using a two way battery switch that completely insulates one system from the other. I installed it inside the coach in my case under dinnett seat just happened to be close to the outside battery drawer auxiliary battery 12v 100 ah AGM (no fumes) to worry about. Plus added a Aili battery capacity gage shunt from the 6v series golf cart main batteries see my post on this forum. See photos happy camping, no worries be happy.
