I'm wondering if any of you guys have a clever idea for how to charge the battery without removing the cowling? I have an external socket on my Cessna 180 that has a special (massive) set of jumper cables that plugs in externally so someone can can pull up next to me in a car/truck and give me a jump start if the battery dies or if I leave the master on. Has anyone done something similar for their RV for both external jumpstarting and/or charging?
