Leaks

[brabono]

Has anyone had leaks in front corners in cab. Not coming from overhead. No wet on wall. Can the side seam covered with rubber bumper strip leak in to floor

You likely have noticed the strips cover the joints of cap/sidewalls. Water can penetrate under those strips and make it to the floor. Seems to me that water can even go uphill at times and maybe it does while rv is in motion during rain. Chasing leaks is frustrating. Check those strips closely and reseal if needed

If you have air horns, you might check where there mounted. My was leaking at the mount and running forward dipping on dash.

Here are some of the places I have found leaks;
Remember: Water travels....

Under the trim where the front/rear cap and sidewall meet.
Inside the sidewall where the manufacturer's foam insulation separated, allowing one to see daylight by the wheel well once the interior wall was removed.
Side windows: remove the windows, install new butyl tape around the edge.
While the window is out, seal the sandwich of luan and foam (or whatever your construction type is) with metal tape to keep any window leaks from dripping down into the walls.
Seams between floor underlayment: Gaps to daylight.
Class A drivers door (riveted in: Drilled out to R&R & re-seal)
Roof vents.
Roof plumbing vents.
Seams where corner trim meet.
Air conditioner seals.
Roof edge molding.
Clearance lights.
Holes drilled by aliens late at night.....
