New Camper evidence of water intrusion

[nondem]

2019 Forest River Vengence 377v Toyhauler.
The slide in the bedroom has what looks like some water staining on the bottom of the slide.

The attached picture gallery shows it pretty well.

The pinion/track thing shown in the pics would seem to be the obvious source but it does have factory sealant along the top edge.
I have found lots of places that need more sealant - the caulking guy at the factory only did the bare minimum ...actually less.
The slide this is on has no plumbing - it holds the dresser/closets for the bedroom.

I'll redo the sealant on the top edge of the rack but I dunno if this might be something coming from inside the slide(hidden by the built in furniture) - sourced in a leak up higher. Possibly hitting the decking inside and flowing out the seam behind this corner.
Do any of you folks have advice on how to locate and isolate the source of this?

This thing is a month old...it isn't permanent damage yet

A window or roof seal leak could cause this. Removing the existing stain with white vinegar after seal repairs will help determine if the leak still exists.

Is the dealer an option?

Go to a SealTech service shop.
