New AI Owner

[ColoradoLady]

In my 2016 Grand Tour 24.5" Ext. AI, there are 2 house batteries underneath the back of the coach and behind the axles. My batteries are Lifeline AGM (gel cell). These batteries run all the coach/house functions.

There are also, in chassis, one battery under hood ( in front of driver) and one battery under driver side floor mat. These are for the Mercedez-Benz chassis functions. This was told to me by the customer warranty service representative at Jackson Center factory.
This information, I take to be true fact....not supposition.

Perfect. Thanks.

This is the main battery that starts the sprinter and makes the lights turn, runs the fridge, etc in the actual house portion. That is all.

I am trying to convince him there is a third battery that controls the house. From reading, it is under the back side seat.

Who is correct?

If you have a battery under the hood that sits on a tray on driver's side you actually have four batteries. The one under the hood is a Mercedes optional Auxiliary 12V battery that only powers the 12V outlet on the inside corner on the driver's seat base. The outlet is under the ultra-leather cover on the seat base. The main starter battery is in a space right under the driver's feet that can only be reached by removing the floor covering and removing the metal cover over the battery. For house power your 2015 LoungeEXT model has two 12V batteries in a metal box under the rear lounge seat on the passenger (curb) side. I'm attaching a diagram of the Lounge model battery box from the 2015 Interstate parts book available on the Airstream web page under service/manuals tab.

Yes.
And to get house batteries open rear doors of the van, remove the vertical carpet cover on the very right corner under the sofa, and unscrew 8 screws (# 1 on the Mike's diagram) of the vertical rectangular metal cover (# 2b ).
The tray with two AGM batteries are there.

Here is the page from the Sprinter owner's manual that shows both the starter and auxiliary batteries.

Those resources help so much!! Thank you! Today is the day we will pull them out and inspect/check them. And replace if necessary.

I think we have a small propane leak. I keep smelling small whiffs of propane around the outside. So, once we get these two things taken care of, we are off on our first adventure.

[sillyRVmom]

Well. So far owning our Airstream has definitely been an adventure!

We finally got the batteries removed today. Surprise!! We have bulging Lifeline batteries.
