Soft floor, Georgie Boy Pursuit, Kitchen side

[Ron Bell]

I own a 35ft double slide 2006 Pursuit, with a big problem now. The floor on the passenger side at the corner of the bedroom slide started being soft a year ago. I thought this might be from water on the awning. Not so as the awning covers the slide very well. The soft area got worse and now has extended to into the hallway, under the fridge area. This is not the shower/bathroom side but the kitchen sink side. I cut the original soft area out this spring and replaced it with plywood.
I have no idea how the rot is originating. It is not from the water lines as the water pump does not come on by itself while dry camping.
The bathroom is on the opposite side (away from the rot).
Any ideas and help would be appreciated. Looks like a major job.
Thanks

could be leaking in from anywhere.... have you checked the roof rail, and the screws or rivets that hold it in place?

Check the areas of the roof over the area too. are any of the walls mushy? Do you notice it getting worse with rain, or are you in a very dry area?

Isn't the awning attached right at the slide on that side of your unit? You could suspect an awning attachment point not being sealed?
