They're probably spec'd to operate over a wider temperature range than household CO alarms, but I'm not sure that's a significant requirement in practice. You're not likely to be spending your time in the RV when it's freezing or super hot inside, which would generally be when it is in storage somewhere. The (household) battery powered smoke/CO combo detectors I have in my RV give false alarms in very very cold conditions; my solution is to remove the batteries when it's closed up for the winter...and, of course, reinstall them before I go camping.
