For some insane reason, our Airstream came from the factory with a single-stage charger. When connected to shore power (or a generator), the converter provides both 12V DC power to the Airstream, and also charges the house batteries. As a single-stage converter, it has only one mode: charge. This single charge mode is neither fast…
Replacing the converter is a great idea. I replaced our 7355 with a Powermax Boondocker so our AGM batteries would not get fried by the stock converter.
You may want to look into a Trimetric battery monitor (http://www.bogartengineering.com/products/TriMetric) if you don’t have anything already. It is a great way to watch your battery usage.

Hi Folks,
I also swapped out the converter and the series 24 batteries with 2 Full River series 27 6volt 220 Amp ADM batteries. They fit in same compartment. You do have to remove the series 24 plastic base holder and the cover to slide them in. Once in re-rivet cover back on. The batteries are great for us, can run furnace all night (lowest 17° outside) and still have 75 to 80% capacity in AM. We use a generator to charge them back up.

Dual 6 Volts are our most likely upgrade. The upgraded converter did a great job reducing our generator usage, which I do appreciate. Though today, my panels did all the charging!
Please add me to your mailing list.
thanks
