Alde glycol expansion tank locations

I keep reading and researching on line for where the tank is that the glycol goes into. I have yet to see a picture of where it is. My T@B is a 2014 and I am sure it has never been maintained. Where do I start?

A 2014 T@B S Max (with bathroom/shower) has the glycol reservoir in the driver’s side rear under the long shelf. There are two (maybe three) square drive screws holding the shelf in place.
A 2015 T@B CSS (Clam shell with bathroom/shower) has the glycol reservoir in the bathroom behind the cargo door behind the toilet.Verna, Columbus, IN

I don't have a bathroom or the clamshell. Can I follow a line to it? I have a 2014 Q. Indoor kitchen, no bath.

The Glycol reservoir in the 2014 is located underneath the rear, driver’s side shelf - secured by two screws.

Hey I think I found it! I can see something while in the corner under the shelf. Now I just have to figure out how to get at it. Thanks!!

@SueDogWalker, I don't know about the 2014 Q model specifically (I am not familiar with it), but your camper photo looks just like a T@B 320S from the outside.............if it is the same general layout inside, maybe these photos will help. When you remove the two screws, the panel slides out toward you.

@Bayliss, the access via the panel was a 2016 model change. The original Alde tanks starting with the 2014 models are under the rear shelf. Here is the only picture I can find.

Here's nuCamp's video, but as noted above the panel to remove varies between model years --

“New to the 2021 320 S and Clamshell models - the tank is behind a panel under the wet-bath sink. White caps cover the screws holding the panel in place.”See photo below, tank is circled in red:
