I've done the blower/soap bubble leak test three times and can't seem to find a leak that finds it's way to the driver's side rear around the bath and bedroom and drips off the cabinet over my bed (not good). I have a 76 rear twin bed, side dry bath Royale. Has anyone had a leak they couldn't find and resorted to removing the gutter cap and found it? It's a long shot and a lot of work but I'm wondering if it might not be leaking in a way that no bubbles show up? I've researched the archives and only find gutter problems with 73s and 74s. Any other ideas would also be greatly appreciated.

Gary,
If you have a roof pod, you might have water leaking from the attachment points of the pod to the roof. I had similar leak issues and chased them for quite some time. During a heavy, driving rain, I would have water coming in above the wardrobe door location and it would run back toward the rear AC unit.
I read here where someone un-bolted their pod from the roof and placed hose washers around the riv-nuts, in the roof, that the pod bolts to. I picked up a package of vinyl hose washers at my local Ace Hardware, removed the bolts on one side of the pod, positioned the washers around the riv-nuts, and bolted it back down. I then repeated the process with the four bolts along the other side of the pod.
A few weeks ago, we got the first of this season's "Monsoon" storms, here in Tucson. Picture being in an automatic car wash for 35 minutes. 50 mph winds and 1.5 inches of rain in 35 minutes. I went out to the coach right after the rain let up and it was bone dry inside. Yay!
I have also sealed the back panel, Jim Bounds style, replaced all the clearance light gaskets, and removed the left rear gutter cap and touched up the sealant under it. I would guess all some or all of these things have helped. The real test will be our next trip that we have rain on.
Good luck

Carl,
Thanks for the reply. My cargo pod was my first suspect. When I first looked at it, I replaced the failed blobs of silicone used around each mounting lag bolt with doubled up rubber washers and increased the size of a couple of bolts to compensate for the stripped holes. I still had a leak. The second attempt was to replace the rubber washers/lag bolts with well nuts. Still have a leak so I don't think it's the pod. It still might be so I may have to just remove it and temporarily seal up the well nuts.
Thanks again

Gary, Mine were sealed inside the pod as well but they still leaked. The hose washers I installed went between the roof and the pod. they provide a gasket around the holes themselves. I would guess that the well nuts would have the same affect, but it would be worth a try to do the additional hose washer trick. It only took about half an hour and cost less than three dollars.
