Sure have, and forgot to turn them off when I went to bed. Woke up the next morning and discovered my mistake, turned them off and waited for the shorepower to recharge my batteries.........However due to a battery isolator, my shore powered converter can't recharge my engine start battery, so I still needed a boost.
We now take a couple strings of small LED Christamas lights that we string up around the coach and across the awning. It looks very festive.
Cheers
Tony
