I'd add to Leon's post that the charged battery would survive IF you leave the trailer closed up (or at least the bathroom walls down). When open, the propane detector, etc. are drawing power, but the kill switch in the bathroom wall will shut them off when the wall is lowered.
And yes, it's a breeze to winterize the trailer (much easier than the Class C motor home I had 30 years ago) -- instructions in the manual don't even mention the water pump -- just open the faucets and then open the drains, though for peace of mind you may want to go a bit beyond the manual, as Leon suggests.
