I cant imagine I am the first to ask about this issue but my searched did not answer my question. It is currently raining .... yay... not so happy when it rains inside the happy Traveller. Only when in motion and are various attemtp to fix it, only when it is really heavy rain. I have lifted the A/C and checked the seal, the new one I bought was wrong size (damm fleabay), existing one was in good condition, not squashed or damaged, leaking started (many months) after a technician had been repairing the unit. So I refitted the unit without any sticky stuff, and tightened the screws to a firmer pressure that what I thought it had been held down to. Many sunny months go by, all good, then out of the blue a big downpour and a wet bed. I have done the flood and drown with the hose, NO LEAKS. light rain no leaks standing or mobile.
I have read about the need for the condensate to be able to exit the unit, i cant believe that it leaks OUT UNDER the seal.... and rain wont come back IN UNDER the seal, the other way.... but experts say it is so.
A/C is mounted on an H frame, front edge of the frame is sealed to the roof so no direct wind pressure, nice upward curve in roof and frame, no pooling.....Van lives in a shed when not in use
I am about to head off into the wild Victorian weather for a few days with a waterproof sheet on the bed..... I would prefer the A/C didnt leak.
Any GOOD ideas or suggestions please. Not ready to buy a different van yet.

Hi Sarge, I had a similar problem but found it was a build up of condensate. When in the tropics we always run the aircon on full fan now. It appears that the condensate collects in that round tube in the bottom half then runs over into the the roof internals and drips out when the unit is run on low fan in humid climate. Hope this helps. Ian
Thanks for your responses, definitely not condensate, we rarely use it for cooling and never for heating, its sole purpose seems to be as a leak point in cold wet windy weather while we are on the move. The Unit structure appears to be intact and self sealed apart from where it joins the roof.
Can't help with a solution, but mine lets water in during violent rain storms or when driving in heavy rain.
There are lots of gaps & cooling vents that undoubtedly let water into the roof unit. I suspect that there are some drain vents/channels that are blocked. One of my between trips repair jobs.
I'll be interested in responses.
I hope that you have more luck than me in solving it.
Of course you could change plans and head north into our warm dry winter.
not much heavy rain this weekend, but so far so good, he extra squeeze on the retaining screws might have done the trick. the $5 tarp was there for insurance.
