Default 2003 Roadtrek 200 Popular AC area leaks when raining

My Roadtrek is on a 2002 Chevy Express cutaway chassis.
See subject and attached pics.

Been parked on a a slight incline for the past 2 days nose down. It's been drizzling off and on. No big downpours or torrents. I have NOT been using the AC. I woke up this morning with the condensation tray under the AC overflowing with (presumably) rainwater on to mattresses and floor. When I looked in (and down) into the tray, I could see about 3/4" of water in it. See pic. I decided to turn the van around and put the rear end of the van down the incline. I could see a lot of water drain out the rear windshield, but I don't know if it came out of an AC drain or off the roof.

To me this indicates two issues.

1. There is a rainwater leak into the AC area SOMEPLACE.

2. The AC condensation tray in not draining properly.

So where to from here ?

Does anyone have an idea where the condensation drain How do I access it? I could blow it out with compressed air.

Where are the likely places the rainwater is getting in? Could it be just because I was on a downward incline for a couple days?

According to what I've read, removing the AC unit is VERY long, difficult task. I don't have any interest in embarking on this.

Thanks for any information you may be able to provide...

I remember discussions about leaks when parked on a downward incline with the front of the vehicle down (nose down). I can't recall what specific models were talked about.

We had this problem in a 2003 model 200 Rosdtrek after the cowl over the AC unit was removed to service the AC unit.
The proper screws and washers were not replaced by the first general RV shop during the repair.
I recall a separate discussion about the drain on some 200 Roadtrek AC compartments being plugged.
As I recall there is a drain tube that can be seen under the RT near the back end. Blowing air or running a wire upward might clear the leak.
I took our RT to a shop that specialized in Roadtreks to have the problem solved. I went to a specialty shop because of concern that if I cleared the clog from below myself might clog again.
Sunshine State RVs near Gainesville is one such Roadtrek specialty shop. (Matt shop manager knows his stuff regarding Roadtreks)

BJ, Thanks for the info. If the Wx warms up a bit, I am going to go up on the roof and remove the cover to see what the issue might be. I understand there are special fasteners called "wellnuts" that are single use fasteners that must be replaced when replacing the cover. I intend on taking one out and getting a set before removing the cover.

Do you have any more information on the location of the drain tube in the rear? A more precise location of where to look for it ?

Thanks.

You must always park nose up, recommended at least 2Ē. If not you will leak when it rains. This is typical, being nose down is the reason for the problem. We have a 2001.

Thank you for the reply Earth,

I guess I have to ask myself "What kind of a whacked out design is THIS" ? Especially for a vehicle that in many cases may be either parked OR travelling nose down during heavy rainfall. ....

I would be very curious for Roadtrek to chime in and confirm that yes, this is in fact, their corporate stance on this, and was their design intention...

WOW !!!!!

I don't recall where the drain hole or holes are within the AC enclosure although I vaguely recall hearing that they may have been funnel shaped and would bet they are in the corners and probably toward the rear but this is just a guess.
Hopefully someone else on the forum can help.
If I find out from the Roadtrek chapter of family motor coach association I will share it.
Again Sunshine State RVs can probably answer the question, or any long time Roadtrek dealership service manager.

Donít shoot the messenger. 😕 I agree, I was pretty surprised when I learned about it.

Earth, no shots fired... Sorry if you inferred that...

I am just astonished at the thought that Roadtrek intended this in their design. Imagine if they did this with their fuel tank. On a long steep incline the fuel ran to the back of the tank, and the engine was (eventually) starved for fuel until you leveled off. Not exactly the same thing, but I'm sure you get my drift.

Doesn't seem like a very good design. The idea of a "rolling home" is to keep you OUT of the elements.

Thanks and again I apologize if you felt I was "shooting the messenger".

Maybe they will chime in with their explanation.

Thinking back, our 2003 RT 200 did not leak from the AC enclosure, even if we were parked nose downhill in rain until a non-Roadtrek maintenance shop removed the AC cover and did not reinstall the appropriate fasteners which are needed to prevent water leak issues.
After the proper fasteners were installed the leak went away.
So I suspect that those who have leaks when nose down may have clogged drains.
By the way our RT 200 was kept most of the year at our home in the Florida Keys where heavyvrsins are common.
