Can't find leak

I apparently developed a leak. The floor in the bunk room near the window has a very noticeable soft spot that seems to be getting worse. It is obviously a leak but can't find where it is coming from. I have noticed some slight delamination on the back wall starting about the halfway mark.
1. There are not water marks on the ceiling or the wall.
2. Rear slide is in immaculate condition.
3. I have never found any standing water inside.
4. Tried running a hose on the roof to identify the leak with no luck.
5. I inspected the caulk on the roof and back wall and have not found and obvious cracks to explain the leak.
Has anyone else run into this issue, if so what did you find? All I can do at this point is re-caulk the entire back end and cross my fingers. I am open to all suggestions.

    You can take it to a dealership, and have it pressurized. They will be able to pinpoint the leak. Then you can figure out what to do.

    Maybe they will depends on the quality of the dealership

    Could be the window, could be the seal around the slide. If other areas look good that would be my next point of concern.

    Sealtech is a national company (franchises) that are able to perform an interior pressurized leak test. You can also DIY if you have a blower that will introduce enough air. I use a furnace squirrel cage blowing in through a window. It develops more pressure than what Sealtech uses.

    look for a U tube that tells you how to do a leak test yourself. ain,t hard,and you already have an idea where it is.

    Have the rig pressure tested - only cost about $100 in my area - they will identify the various points of entry and likely give you and estimate for fixing. DIY is fine .. but you want to find the leak ASAP and it doesn't cost that much to have a pro do this test.

    I had a water problem on my camper. i could not find any places that water could be coming in until I removed the rubber strip along the gutter rail and found that a large number of the screws were rusty and loose. its seems that water was wicking into these loose screw holes and seeping down into the wall. after a heavy rain I would discover water stains on the door sill, the window sills and any where there was an opening in the wall. I eventually replaced all the screws in the strips with stainless screws,applied caulk to them when i replaced them and made sure the screws were tightened sufficiently. end result, stopped all the water leaks.

    Thanks for all the suggestions. I have rechaulked the roof joint at the real wall. Don't know if this will solve the problem or not. I will definately investigate the Sealtech pressurization.
