Axis. water leaking from chassis A/C

Short:
Where is the drain for the Chassis A/C in front of the passenger seat and over the front passenger wheel? I think it's blocked.


Long version:
Just got back from our 2nd trip in our 2017 AXIS 25.2. Love this thing!
We stopped for dinner and when we came out, I saw a lot of water dripping from the bottom, around the engine.

I was really concerned because I thought the engine was running hotter than I thought it should. I'll ask about that later.

So I figured coolant issue right off the bat. Looking underneath, the water was dripping from several places. I smelled the water and it didn't smell like anything. Didn't smell like antifreeze. That was a relief already. After opening the front grill and the doghouse inside I couldn't see anything. I then managed to crawl underneath right behind the passenger wheel. The water was coming from above the top of the passenger wheel well. It was running all over and dripping just because of the angle I was parked on. I removed a panel and could see it. The water looked to be coming from the vent box of the A/C and looked like from where a hose was coming out. At this point I was very relieved. I put everything back together to finish our trip. I'm assuming there is a blocked A/C drain. I've Googled 2016 Ford E450 chassis AC drain but I'm not finding anything. Does anyone know where it is before I start exploring? Not an easy area to get to.

Other question:
I have the ultra scan gauge with the engine coolant temp. Our first trip it averaged between 195 and 199 degrees. THis trip is was the same going from NJ to Fl. Coming back the first day I was getting temps from 198 to 208. Mostly 203 to 205. It was the hottest day that we've driven it so far. Today the outside temps were lower and the coolant temps were back under 200. Anything sound concerning about these temps?

50/50 antifreeze boils at 223F. Add a 16 psi radiator cap and you have 257 F boil over.

AC condenser produces water. Is it draining inside onto the floor? Or is it all outside? May be normal. Based on your coolant temps sounds like it was hotter and maybe more humid )Florida).

It's leaking outside which I know is normal. It appeared to be leaking from where a vent hose comes out of the vent box. There was a lot of water that came out because of the way it was parked. I'm thinking a drain is clogged,it filled with water and poured out when parked on an angle. I'm gonna try to find where it's supposed to drain from today.

If you've ever removed the passenger side front desk/work station area in your Axis/Vegas to access the chassis battery you will see where the condensation exits the AC box

There's a hole on the underside of the box
Currently the condensation drips on the top of the plastic wheel well cover and finds it's own path out

I believe that the drain hole can accommodate a small diameter hose so that you can route the condensation to your desired location

Thanks!. It was leaking on top of that plastic wheel cover but definitely coming out of the wrong place and way too much water. There was a little tube sticking out the bottom of that box so I'm going to try to see if that is supposed to be the drain. I'll take a picture of it.
