Winter storage AGM battery question

I live in northern NM mountains, where winter temp in the teens are common, and on occasions, sub zero. In the past, I kept my '01 TK at home, winterized, and AGM batteries disconnected.
At 2 or 3 week intervals, hook to shore power for a day or two. (Has new 45amp 4 stage convertor) This  winter I plan to store the LD inside a friends warehouse in town, as a couple of trips are planned for a week  or so during the winter.  Snow and ice can be a problem getting the LD out , and there are 3 miles of dirt road, so in town is  a great option for protection and travel flexibility.

I am not able to leave the LD hooked to shore power  permanently, but can go in and hook up for about 6 hrs periodically. Would 6 hrs hooked up every week or  ten days maintain a  safe level of  charge on the AGM's?  Batteries would be disconnected  so as to minimize draw .  LD will be winterized as  the warehouse is not heated.
Thanks for any recommendations.  Wayne

Hi Wayne,
 Your batteries can go months in cold weather without requiring charging, losing only 1% of their charge per month in at 35 deg F and lower, so you don't need to charge it so long or so often.

 Thanks Eric: Since  getting shore power to the LD in the warehouse in which it will  be stored for the winter is  somewhat of a hassle, and I would have to occupy myself in town to disconnect I will just not bother.  As I mentioned, a couple of trips are  planned during the winter  (AZ or S.TX to warm up) so  the LD will not be in storage for the entire winter.

Wayne,
 If your AGM batteries are fully charged when you put your rig into storage, they will NOT freeze. Period.  There is nothing to drain the batteries if you disconnect them. AGM and the Mothership says, that our rig, stored here in Alaska for 6-7 months, will not freeze if disconnected and is fully charged. There is nothing to drain the batteries if they are disconnected.
No re-charging like the water based batteries of old.  You will do fine.
