I tow a Sprite Tourer SP with a 2009 Defender Puma 2.4. My tow combination for the past 4 years. The Tourer comes standard with aNational Luna week ender 50lt fridge/freezer and the caravan battery is charged via a BH plug from the Defender’s battery through the normal caravan electrical set-up.
I also have a National Luna Power pack and a Dometic CF 50 fridge/freezer for the Defender.
Question. Can I run both the Caravan charge system and the National Luna power pack from the Defender battery or should I have a stronger alternator installed. I do not run them simultaneously at present. We are not “December” campers but do sight seeing and exploring trips when on holiday.
