05 9400I 52 in sleeper leaking into bunk

sleeper leaking water into bunk when it rains, left hand side behind driver seat. seems to be coming from along the shelf on back side of bunk, have a wardrobe cabinet, where it meets the shelf water comes in somewhere around there.

I've caulked everything I can think may allow water in on the back of the truck, above and below seams of drip edge, bolts, hand rails and such.

is there anything I can do to try and locate this leak, aside from tearing out the interior?

Or any known leak points I can check?

thanks in advance

found a crack in the sealant under the drip edge on the drivers side, just in front of the rear air wing, could be the culprit, caulked it, sprayed water on it, not seeing any leak, I'll have to wait for some rain before I'll know for sure.

thanks for the come back Heavy D.

let you know

 

ya I'm thinking this is whats going on, doesn't seem to be anything in the back that would let water in, or where it's showing up anyway. so the crack along the side drip edge is the only place I could find that may.

now just waiting for the rain...
as crazy as that sounds...

thanks HeavyD
