Rpod 177 rear window leak

I purchased my very first camper last year (used 2013 Rpod 177), and did not have any leaks during rain when it was parked in my driveway, or at the campground ... up until last weekend. On sunday night, we drove back home in heavy rain, and when I went to clean the camper I found the bed very wet. Luckily, I caught the leak the same day, I had a sleeping bag covering the bed which absorbed most of the water, and the water did not make it to the wooden panel under the bed. I have been spinning my wheels trying to figure out where this leak is coming from because the roof is dry, and the corners are dry. I noticed water around the inside frame of rear window (the one that doesn't open), and I found some forums here that talk about those weeping holes not draining properly because of the way the manufacturer installed a flat window over a curved wall. I checked the seals around the window and they appear good on the top and sided, except the bottom doesn't have any sealant, but I read that it is supposed to be that way. I'm becoming convinced that the leak came from the window, and I used a wire to make sure the weep wholes are not clogged, but somehow water did not drain properly while driving. How can water collect in the rear window frame when it is a solid window? If the window already has the weep holes, how can you improve the drainage of rain water? The rpod repair shop is quoting me $1750 to repair all the seals, but I would hate to spend that money and get water leaked again because the issue is in the rear window. Please advise.

How would you know if the leak is coming from the spoiler? Are you thinking the water is getting inside the wall thru the spoiler and down to the window frame? I didn't see any water in the ceiling or the wall above rear window.

Hi Isabelisa! Sorry to hear about the leak. We were camping last weekend as well, also in the same heavy rain and experienced a bit of interior moisture on the windows when we woke up in the morning from condensation. The end result was the same. The condensation on the back window pooled in the window well and poured out onto the back bed when we moved the camper. Not sure if the same happened to you but something you might try is using a garden to find the leak. Start at the bottom of the rear window first, then each side individually, then the top. I would suspect if there is a leak, it would present itself when applying a bit of pressurized water around the seams of the window. 

More reason to suspect spoiler. Those leaks can be really tricky. When my spoiler leaked the only indication I got was floor of trailer on the bottom, at very rear of trailer was wet. I was installing back-up lights when I found floor soaked.
