How many of us are there? Owners of Dodge based RV's?

Yes I'm going to get me a better charger Friday and I will look into getting a deep cycle battery Friday as well the battery I have now was pretty pricy for a battery so im going use it till it's dead lol but will have that deep cycle battery ready when it is time. Do u think that the battery would be to much to run off of the altinator if I were to hook it up to my rv battery so the house battery stays 100% while we are driving till we stop?
