Gene,
The dual golf cart batteries (2 6 volts = 12) is the most durable setup
for the GMC. Interstate and Trojan are the most popular brands in use
and you want to get at least the 225 or better amp hour battery. If you
still have the old buzz box read on.
The original converter is not a very good charger, has a tendency to
overcharge and gas out your batteries causing them to fail sooner than
later. I have been very impressed with my Statpower 40 and its
operation, it is truly a smart unit. I will admit that I also was
unaware of the fan noise until I got it installed and running. Although
you can hear the fan running at times after awhile I almost don't hear
it run. The auto charging and holding the batteries at charge and
providing all the DC power you can use without draining the batteries
while plugged into house power is great. Todd also makes a
converter/charger which cost more that the 40. It also has a fan, but I
will admit that I know very little about it. Max at Buskirks has one
installed in his coach. The use of a battery charger to charge your
house batteries will not be much better than using the old buzz box that
you already own. The battery charge will shorten the life of your
batteries because you will gas them out every time. I am going to make
a statement here, "It's not how you charge your batteries, but HOW you
charge them". The Statpower 40 goes thru a charging sequence that does
not stress the battery and thru the charge cycle will take the battery
to almost 100% charge. Using a regular battery charger the most you
could expect to recover is about 80% of useful charge. If you need to
hitch an external charger to your batteries, consider them as one big
battery and you hitch the positive to the terminal that your house
positive is hitch to and the negative to chassis. We can type more on
this if you wish.
