yep, assuming that the battery is full, when you picked it up from the dealer and assuming that your tow vehicle will recharge it in 3 hours, is not a good thing.
if it didn't have a battery disconnect switch or the dealer didn't keep it plugged in, the battery could have been below 50% charged.
and, at best, most tow vehicles only trickle charge a battery while driving. so 3 hours may only have made a dent if the battery was that low.
