Not sure why they would want shut off for the outside shower. So the only two low point drains on yours is on the curb side rear side dual?

Yup, that's correct. Passenger side, rear, under cup holder.

The answer to your questions on the Aux battery are contained at page 3 (Overview) of the Sprinter Engineering document on installing the Auxiliary Battery. it says:
"When installing electrical aftermarket equipment with an AMP draw of more than 25A in Mercedes-Benz Sprinters & Freightliner Sprinters it is necessary to use the optional aux battery 12V/100Ah (CODE E28)."

There are over 25 Amps of added equipment in the new Interstates powered by Sprinter battery, including these items with fuse ratings:
Awning (20 Amp)
Slide-out Step (10 Amp)
Rear View Camera (15 Amp)
Kenwwood DNN990HD (5 Amp)
12V Outlet on Driver Seat Base (15 Amp)
Trailer Brakes (if installed by owner, can draw up to 30 Amps)

I've attached a document containing pages from the Sprinter Equipment Book that gives you a sense of how the Auxiliary Battery is used.

Interesting as the new 2015 owner's manual on page 9-15 states: "There are three fresh water line low point drain valves. There is one under the galley accessed by removing the drawer in the lounge model, there two under the curbside lounge model accessed by removing the cupholders."

Curious as to what the single low point drain valve under the galley is for.

I'm curious, can you post a photo of these valves?

In reply to Boxster1971, I did follow the earlier link, and I agree about the extra battery. I guess I was thinking that most of those things you mentioned were powered by the house batteries, and not the chassis battery. However, I certainly see that the possible trailer connection alone would immediately account for the extra load all by itself.
As for 73shark, that's just one more example (there are so many, and even some glaring typos) of why the manual is almost totally useless. There is no valve under the sink, at least not that I can see. Yes, mine is a Grand Tour, and almost everything important has been moved around from earlier models. I would be happy to post a picture, but I put the "breadbox" away in the storage yard for the next few weeks, so I'll do it when I wake her up for some exercise. Unless someone else beats me to it.....

.....

All the items I listed, except the Kenwood DNN990HD, are powered by the Sprinter starter battery. The Kenwood is also powered by the starter battery when the coach battery is turned off. If there is an Auxiliary Battery option like you have the cut-off relay switches all these loads to the auxiliary battery when the engine is shut down. This is a very good thing to have installed in your Interstate.

The trailer brakes would likely only be used when the engine is running.

Personally I think the new self retracting awning probably pushed the limit to convince Airstream to add the auxiliary battery. While camping I could easily envision a scenario where you would cycle the awning several times a day.

Hope some of this info is useful,

FWIW, the solar panel and/or the generator will keep the chassis battery charged on mine.

The ones that count are the ones that might be running when the engine is off. Namely the sliding step, the awning, the 12v outlet, and possibly the Kenwood. These items all ought to be wired to the auxiliary battery under the hood, if you have one, so that they don't run down the starter battery.

When the engine is on, the rear-view camera and the trailer brakes would be powered by the alternator, not the batteries, and so do not need to be wired to the auxiliary battery. They can't run down the starter battery.

When you say "chassis" battery, do you mean the starting battery or the auxiliary battery? Because of the relay that only connects the auxiliary battery and starter battery when the engine is on, so that both can charge from the alternator, I do not believe the solar panel, generator, or shore power will charge the auxiliary battery, only the starter battery.

Since mine is a 2011/2010, it only has a starting battery which up 'til the 2015 was all they had AFAIK. Most folks 'til now have referred to it as the "chassis" battery. I guess now I'll have to be more specific.

Since we camp frequently and always travel with a water supply, we, too, like to cycle through the on board fresh water as often as possible to keep it fresh. We have begun using the water pump and fresh water tank most of the time....even at sites with water hookups...when the tank runs low we fill it up again using the exterior fill port ... and top it off before we move to a new location. If we are in an unfamiliar place we use an in-line filter to fill the fresh water tank.

Then once in a while we'll hook up to the city water (again, using a filter) just to keep everything in use at least some of the time.

Also once in a while we add a half-ounce of bleach (this can vary with larger tanks) to the fresh water when we fill it up ... just to keep it sanitized and fresh.

This routine has worked well for us and we've never had a problem with bad-tasting water.

Inline filter is a great idea. Can you provide a brand name and/or photo, please?
