Sometimes it is convenient to trade some cargo space for extra battery capacity. I repurposed the original starting battery that the group-31 upgrade replaced.
Back-country travelers are using Amateur Radio for wilderness communications because of the greater range. Many have a Citizen Band radio because it is ubiquitous even though the range is limited.
To charge our Casita travel trailer, Cocoon, we added a power connection to Campbell, our Toyota Land Cruiser. We also added a power distribution center in the cargo area to run additional gear.
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.
