First a disclaimer on my part, I'm not familiar in detail with the 178 plumbing routings, I have a 179.

Next, a dumb question, has it been raining while you've been there? You're obviously having plumbing difficulties but let's also rule out other sources of water intrusion.

Third, my recommendation is to actually look at the fresh water tank under your rPod and not trust the little sensors, they can be inaccurate. The fresh tank is translucent so you can easily see how much water is in it.

I believe all your plumbing equipment is in the rear of the 178 so if any of that is leaking then the water can run all over the area under the bed and in the storage areas. Enough water to get the tips of your fingers wet is a lot of water if its spread out back there. 

A couple of things you should do right away. Don't reconnect the city water. Run some water out of the fresh tank if it is full/overfull. Then, leave the water pump off.  You want to stop any more leaking before you have more problems due to water damage to the floor. 

Pull up the mattress and plywood to expose any wet areas around the furnace/pump/water heater area and dry up any visible water there and in the underbed storage. Get a little portable electric heater (assuming its not warm enough to just run a fan) and try to use it to get everything dried out. 

All the above is to try to get things dried out, it won't of course stop the leak itself. So getting back to that most likely the problem is that the check valve in your water pump that keeps city water from flowing back to the tank has failed. Usually that will result in the tank overflowing out the tank fill fitting but you're getting leaking elsewhere. And the usual temporary fix is to do what you already tried, just stop using the city water. 

That might have already worked and you're just seeing residual water from before you shut the city water off, or from the tank being too full. Or, you could have a leak somewhere in addition to the check valve problem. Either way, I think you have to get things dried out a bit so you can find out if there is still a leak and where it is. The pump itself and its fittings is a good place to start. 

Good luck, and others as they come on line today will have additional suggestions for you.

100% agree with Mike and his thought process.  If you pull your mattress off, you can remove the first panel of plywood (about 4 screws) and the access panel under the sink, then everything you need to see for water access is right in those areas.  

I would agree with earlier comments and suspect that your check valve is bypassing water and you likely have a leak there as well.  The water in your storage compartment would be coming from that same area and just flowing back.  

Hope you figure it out, nothing more frustrating than water leaks.

Yes, BoulderGal has both a highly probable check valve failure and a leak, plus a third issue stemming from the leak, which are wet floors over a large area.  I'd like to be sure she gets that dried out before she has water damage problems on top of plumbing problems. The leak could I suppose be related to the overfull tank as well (overflow line leaking perhaps). 

Thanks!!!!

If I can get it to stop raining for even one day (this IS the Pacific NW) I will look into locating the pump.  Unfortunately, the Forest River manual is short on details as it appears it's the same one for every model.  Sure wish I could get my hands on a schematic.  Just call me "Jane of all Trades" and wishing someone was here to help!

The issue of "freshness" is somewhat subjective and dependent on the original source for each. We like to take along our own fresh water on some trips, as we really like our well water, and it's a known good source. City water is "usually" OK, but it can be an issue some places.

Just be sure to put your latrine down stream from camp and get your water up stream.

I've spent enough time in developing countries that I never drink tap water anyway, even at home or in the pod. Bottled water in the pod and filtered at home. There used to be lots of places you couldn't get bottled water, or it was suspect, but beer and cola is pretty much everywhere. I learned early on that I much preferred to brush my teeth with beer than Coke.....

BoulderGal, I think you've got your original problem under control, as in you have water and no active plumbing leaks. As mcarter says, no rush anymore on that.  An rPod is small but it still has pretty much all the same systems you have at home, ergo, it has similar maintenance requirements. 

The A/C leak could be due to the horizontal rain you tend to get on the OR coast. We get that horizontal rain in coastal NC too. The a/c cover comes off pretty easily if you can get a dry day without wind to get up on the roof. Clean out any leaves and crud that's gotten in there and be sure the condensation drain is open. That usually does it for me. 

In the pod I just use the 2-1/2 gallon water bottles with built in dispenser, one sits on the counter next to the door, the expense is really insignificant in the overall scheme of things. When travelling they go in the right rear storage area under the slove in the 179, helps reduce the tongue weight!

Liquids don't have to be cold to hydrate, I generally just don't worry about that. Trying to cool very much water or make much ice is beyond the capabilities of our absorption fridges anyway, especially in warm weather. 

Hmmm...Think I'll stick with my store bought 2 1/2 gallon dispensers...

 The testing of San Francisco and Oakland water, from the Sierras, is way cleaner than most bottled water.  I went to a bottling plant in SF back in the early 70's to get some 5 gal. glass jars to make beer and found them filling the water bottles from a regular tap water source.

  

I'd still suggest starting by taking off he a/c cover and cleaning and inspecting under there (between storms). The a/c sits on a small standard 14x14 inch square cutout like the one the bath vent is in, so generally its pretty easy to see what's causing the leak. Lots of times its the condensate pan drain (which is supposed to drain onto the roof and down the side of the trailer) which is clogged. 

Sometimes being a "Jane of all trades" gets really old!

Mine is cracked and needs replacement as it's temporarily taped with Eternabond tape that i have had on there about a year.  Later today, I'm going to start the search for the replacement.  I called Dometic once and they gave me some of the information about the unit, but they consider it obsolete even though it's a 2009 trailer.  

Sounds like your leak is, as was suggested by Marwayne, is related to the seal between the roof and air conditioner.  Best of luck in figuring it out.

Take out the filters first then the screws.

The top shroud is how held in place with 3 bolts - one to the rear and two to the front.  Mine were extremely loose.  So, all tightened down, all that I can see dried off, it's pouring outside and I'm waiting to see the results!

Thanks to ALL, especially for the excellent photo and information about the correct type of screwdrivers.

My 2015 178 is leaking in THE FRONT behind the aluminum diamond plate shield. I bought my RPod knowing there was a leak there, thinking I could figure out the problem on my own as I am generally handy with a tool but this has me stumped. The air conditioner seems to be weeping appropriately with no visible means of ingress along the rail, in fact the water doesn't appear to be even coming in contact with it (yes, it's properly balanced) and the shield appears to be well sealed. The wood behind the shield, which I must confess I was surprised to see since I expected to see aluminum framing, is beginning to rot.    Any ideas?
