We had a fantastic day for a quick day-trip and picnic to Potrerillos with the truck. It was the opportunity to test the charging system. The secondary battery was showing a full charge when we got there. Since there isn’t much draw yet, we have to wait until a fridge is hooked-up to really evaluate the system, but so far it is encouraging. We cooked pasta on the tailgate since the weather was very nice, but we ate inside on the table and did the dishes in the sink to check the water pump. All went well. Below is the link to a short video I made.
