I'm quick with my flashlight to spot any interior dampness that may have breached the seal. The good news is, the slide seal is weather tight! The bad news is I found a steady stream of water coming down my genny roof exhaust. As many of you know the genny roof exhaust is encased in a 4" stainless steel pipe as it routes it's way thru the bus interior. The stainless is wrapped with a reflective insulation. Water is streaming down outside surface of the insulation wrapping. I have yet to climb on the roof to look around, too much lightening, but I thing it's designed so that rain can run down the void between the genny exhaust and the stainless steel outer pipe. This doesn't seem to be my problem. My leak seams to be on the outside face of the stainless steel protective piping. Have any of you experienced genny exhaust water leaks of this type? What should I check for? Are roof caps available where the exhaust protrudes thru the roof and seals onto the roof surface?

The plastic (pvc) nacelle that encases the genny exhaust pipe distorted and lifted from the roof of the bus. A quick bead of urethane solves the problem but the nacelle is cracked and should be replaced. Anyone know of a supplier for this piece? It can be repaired with urethane, but it'd be interesting to see if a replacement is available. Maybe I'll get on the phone with my local school bus franchise to see about a vendor.

Here's a couple pics of mine. The bright white in the photo is some makeshift plumbers putty that I globbed on to temporarily stop the leak. My guess is that BB used this piece on all Wanderlodges with roof exiting exhausts. This coming week I'll make some phone calls to see about a replacement. Now I need to climb back on the roof to see about a manufacturer or a part number that might be stamped on the nacelle. Mine's plastic - yours may be metal.
