Thanks for all the information. This is a new Motorhome for us. 2007 Georgetown M-350 Bunk model. I'm sure the batteries could use replaced and we will look into Solar also. Gonna check the battery bay and make sure we don't have room for 2 more Deep 6v batteries.. Thank you for all the information. Only asking cause this has been an issue with every RV we have ever owned. We have had 2 Toyhauler trailers and this is our second Motorhome and all have had batteries that died if running heat at night. Time to get this one figured out. Thanks..
