Airstream has a 3 stage charger with the converter for the 1998 . There is a lot of talk on the forum about overcharging, but, some of us are OK with the stock equipment. I have the 32 amp model with option "C" (means has the charger). NO worries. But, I don`t think the solar would be regulated without an aftermarket controller. I am getting mixed opinions about it. Anyone done it with a 97-99 model? Thanks if you can settle this.
