I had an old one about that vintage for awhile. I was surprised to find that the ac/dc convertor didn't charge all the batteries, and the ones that it did charge got overcharged while plugged in between uses. Replacing that converter would have saved some battery money, and adding a small battery tender to the chassis (starting) battery, too. The new converter on my present motorhome charges acceptably as is.
As they say, 'bring a toolbox and a good attitude' and you'll enjoy owning a motorhome. You'll learn a lot on this forum.
