Not totally travel-related.
Our 30A DC-DC converter that charges the LiFePO4 battery from the alternator was getting too hot. Fortunately we didn't need it with the solar over the last summer.
I've mounted a computer fan behind the heat sink along with a 50°C thermal switch and it works perfectly!
It took 20 mins of charging to get from 20°C to 50°C, the fan came on and cooled it back to 35°C in 90 seconds. It takes around 10 mins to climb back again. Rinse, repeat.
