[A/S] Battery Chargers

[baryfrnkln@xxxxxxxxxxx]

Advice needed... Ok, I've finally determined that my 30 year 
old Univolt System, although humming, is not charging my battery. At 
this point, I would just like to replace it with a new system that I 
don't have to worry about. I have been corresponding with an Airstream 
owner in California that is simply using a marine battery charging 
system, and is even using two batteries with an isolator. My question 
is...

What has anyone used to replace their Univolt system? 
What kind of cost is involved? I've seen units in the Camping World 
catalog for a few hundred dollars. Some of the marine chargers are 
only $60-90. Am I missing something?

It is my novice understanding that when plugged in to shore power with 
my univolt, it should be charging my battery and putting out a solid 
12V, as well as sending 120V to the main outlets and non 12V 
appliances. Correct?

As always, the information posted here is as the Master Card 
commercial says.... PRICELESS! I'll look forward to all of your 
inputs.
