Episode 2: Sulfur smell again. Took it to service. They stated the brand new batteries were out of water so they replaced them with waterless batteries.
Episode 3: Sulfur smell again for a few hours on the new batteries, then it stopped. Took it to service, they consulted with Airstream and said there is nothing wrong.
During all of this, the house battery will not hold a charge overnight. Service center says nothing is wrong. Is it unreasonable for us to expect the battery to last overnight with only the small refrigerator running? Does everyone else that owns an Interstate wake up to a warm refrigerator?
Since the batteries can't apparently be fixed, we thought about switching the refrigerator to a propane refrigerator (a bandaid fix, I believe), but Airstream said it can't be done.
Can anyone help? We are desperate! We spent $80K on this rig and can't trust it to last or not burn up (sulfur smell - isn't that a symptom of overheating batteries?).
You have a problem with your charging system that might/might not be converter related. YES, the Parallax converter that I believe came in the T1N Sprinters is garbage, but unless you have been running your generator continuously or have been on constant shore power, it sounds like you have other issues as evidenced by your 'sulfur smell while driving' since the only charge source for these batteries while on the road is your engine alternator.
You should have your charging system (including your engine alternator and your battery isolator/separator and or the battery isolation device) thoroughly checked by a competent and experienced
I think that your problem is deeper than you have been led to believe.
