Depends if you have a 2 or 3 stage converter/charger in your TT. I believe the new 2011 models have the Progressive Dynamics converter/chargers that include the Charge Wizard (3 stage) and would better maintain your battery with shore power than a 2 stage unit. Just check the water level once in awhile.
If you have the remote IOTA DLS Converter/Charger, then it's a 2 stage unit ($20 to make it a 3 stage, use this: http://www.iotaengineering.com/iq.htm
As mentioned, extremely cold weather can have an effect on some batteries, so keep a close eye on it should this be the case.
