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.
I installed a Backroad Raspberry (BRRB) and a dedicated Wi-Fi network in Campbell. The BRRB is powered by an auxiliary battery and uses 6.7 watts, including the router.
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.
