We upgraded the starting battery in Campbell, our Toyota Land Cruiser. Even though we added an auxiliary battery to run our dry-camping needs, the main battery must handle a considerable load, especially with a winch.
We want to use our microwave when we are boondocking in Cocoon, our Casita travel trailer. We need an inverter for that but do not want to add a new load to our single 100-amp-hour house battery.
To juice up our power-hungry gear on excursions away from base camp, we added a second battery to Campbell, our Toyota Land Cruiser. The extra power will also be helpful while we are boondocking in Cocoon, our Casita travel trailer.
