2011 heartland prowler battery size

[Jasindude1]

What is the factory battery size for this rig? I have a DC24MF that came with the camper. But last year on a hunt my camper heater couldn’t even run all thru the night. I need to know if this is even big enough for my camper or if I need to double up on batteries.

If you have the space I would go with two 6 volt batteries, that would give you about 230 Amp hours vs about 80 Amp hours with the group 24's.
