coach battery issue ?

Hi all, I have a 2009 Pleasure Way Excel class B RV. I just replaced the coach battery with a new one of the same type as the original (Interstate). Before the trip when doing my pre trip inspection and prep I checked the charge on the coach battery and it showed 12.6 volts (a full charge). After about a week trip and getting home, about a 2.5 hour drive, I noticed that the coach battery indicator in the RV only showed that the coach battery was only partially charged. I put my digital voltmeter on the terminals and indeed it only showed 11.99 volts (about a 40% charge). I would think that a new coach battery after a 2.5 hour drive would be fully charged (about 12.6 volts). Do I have a problem with the coach battery charging system or perhaps the battery itself. I did have the Dometic small refrigerator running on DC while driving as usual. Is this normal or do I need to take it in and have the new battery checked and the coach battery charging system? Just wondering because I thought it would be fully charged after that drive home. Thanks all...Don.
