I'd recommend 4 of these at a total of 88AH.
Good info here:

Once there, scroll down.

But then, you don't say what you're going to be using the aux set up to
support.
Audio may not take much, or may take a lot depending on what you are using
your van for. Some of us stay put in very remote locations for several days,
then
drive to another site and do the same again. 44AH won't support much without
some sort of recharging system, which information is what you need to
include
if you're going to get useful-to-your-specific uses information and
suggestions.

I have quite a bit less than $200. invested in my aux set up and it works
great
...... for me.
