Leaks

[johntk]

2021 Winnebago 29b

MH is leaking in the front passenger side. The workstation gets a lot of water in it when it rains. We have been all over the inside ceiling/bed/walls and cannot find any trace of leakage. Water does leak around the passenger window but I can't find a way it could jump into the well of the work station. This is occurring while parked. I've never noticed it when traveling.
I will appreciate any ideas/comments/input.

Thanks,
John

Don't know what the workstation is... guess it might be a pull out tray for the passenger seat?

Mask off areas outside and then remove masking until the leak shows up again.

Typical areas on MHs include; clearance lights, horns, antenna mounts, windshield gasket/seal, windshield wracked/rotted, seal between roof and sidewall and nearly anything on the roof within 8' radius.

Get a large box fan and tape in a window with the fan exhaust facing inside. The fan will pressurize the interior then spray a soapy solution over any suspect place (which would be any roof penetration, joint, seam, etc.)

Water intrusion can happen a long way from where the leak actually presents itself.

I had a piece of molding on the outside of the RV. That didn't come together and it would leak in there.
