Where does refrigerator condensation drain go?

I see the refrigerator drain line enter the floor above the wheel well.
Where does it go from there?
Does it tie into the a/c drain line?
Does it go into the gray tank?
I can see the condensation drain for the front a/c in the wheel well ahead of the front tire and the condensation drain for the rear a/c in the wheel well behind the rear tire.
Things that make me go hmm...
An RV repair shop recently installed a new PEX drain line to replace the dry rotted original refrigerator drain. Was the whitish looking piece of tubing going into the floor with putty around it already there?

My frig sits just forward of the right rear tires, it has a white tube that drains directly below it. Sometimes I see a small spot of water but nothing major. Only condensate lines that run to holding tanks are the AC.

I am going to assume yours is the same as my 2007. The fridge drain is more centered and inboard of the wheels than the A/C drain. It looks the same as the A/C drain but is inboard of the main frame rail and wheel house, probably right around the end of the fresh water tank pan.

If it's "lost", due to your service, pour a cup of water in the fridge drain tray and inspect under the trailer.

I tried pouring water in the condensate drain pan in the refrigerator.
I still couldn't determine where it exited the trailer.

I could not see the water draining under the trailer at all.
No dripping.
No wet spot on the ground.

that's not good!

OK, again, assuming yours is like mine, I assume it goes through the fridge compartment door just left of center when looking at the back of the fridge.?? Go inside and pull out the drawer under the fridge and set it aside. Look up at the underside of the fridge compartment floor between the top of the wheel well and the fridge floor. You should see white pex come down and make a 90* turn to run along the wheel well top. IIRC, it goes through the floor and through the belly pan along side of the wheel well. If it stops raining, I'll run out and verify.

I do not have a Classic, mine just drains into the outside compartment with the refrig stuff and dribbles down the side.

I see the white pex line coming straight out of the back of the refrigerator then to a 45 degree elbow and straight down through the floor of the refrigerator compartment.
There is no corresponding hole anywhere in the wheel well or under the trailer that I can see.
I was not even able to get an answer from Airstream.
I guess the next time I am at a dealership service center I will get them to look at it, decipher it, and tell me what's up.

OK, here we go...this pic is looking in the outside access door. The corrugated line comes from the fridge tray cup to the white Pex line sticking up through the fridge compartment floor:

From there it makes a 90* bend across the top of the LF wheel well, at an angle and another 90* bend down the well face. This pic is taken from the area under the fridge floor, with the drawer removed:

From there , the line makes another 90* turn to be parallel and lying on the AS floor, angled toward the front and disappears through the back wall of the rear dinette seat backrest. Here you can see it make its final 90* turn down. You can see the last elbow in the next 3 pics. These pics are taken with the rear dinette seat drawer pulled all the way out. Note the relationship of this lats elbow to the LF wheel...toward its front half and substantially inboard of the wheel and frame member:

I'm sorry, I didn't take a pic from underneath, as there is about an inch of slush on the ground and although I love ya', I don't love ya' that much!
But the white pex just passes through the cross trailer utility tray and belly right below that last elbow. Hope this helps.

How many feet fore/aft port/starboard of the refrigerator?
For some reason I thought it would exit under the trailer in the general vicinity of the refrigerator.
I guess it isn't that simple.
I would go crawl around and look but it is dark and it rained earlier.
