I've been reading the comments about analog vs. digital chargers.  Interesting!

Does anyone have experience with the Promariner Prosport line?  In my
'84 camper, I recently installed a 44AH deep cycle aux battery and a
Promariner Prosport 12 that automatically charges both batteries when
shore power is plugged in:

I haven't used it much yet.  Anything I should look out for?  It
seems to do the job, but I haven't yet camped long enough to really
run down the aux battery.

When I installed the aux battery, I added an ammeter shunt in the
main feed.  I'm curious to monitor the load/charge current.  I used
this Westach kit (just because I like the Westach stuff I've
installed in light aircraft):

I bought a second shunt for the starter battery, but I haven't found
a good place to install it yet.  The starter battery takes up all of
the space in the compartment beneath the passenger seat.

I haven't installed the meter itself yet.  I thought I might
fabricate a replacement monitor panel and mount the meter in place of
the battery lights, with a switch to select between the two shunts.
