I search all of the threads on this topic, but still have a couple of questions. How much current do the hard-wired combo units draw and is it just better to go with separate battery units with the propane detector mounted near the floor and the C0 detector mounted at sleeping level? I know that the current draw might be moot, but get several gadgets drawing .1 amps and don't drive the camper for a few weeks and you have a low battery.
Thanks,
