AC condensation run off

When the ac runs it creates a lot of water/condensation that is currently running to the front right corner of the vehicle on the roof. Is there a way to divert or add a condensate line to the AC and prevent the water from running across the roof. Thanks

  • Our rig has rain gutters that run along the two sides. A/C water finds it's way there from the crowned roof and then drips off the gutter to the ground.

    You can see the gutter here but the gutter opening was not captured. It has an extender on it maybe 1/2" or so to drip away from the side wall.

    Maybe you can add them to your rig.

    I have placed some small aluminum right angle strips to divert run off to the roof side drains. GLued them down in place with DICOR...

    This was mainly to prevent run-off from coming down the back rear window area of my 5th wheel.

  • Roof doesn't care if it is rain water or from a AC that gets on it.
    As long you keep checking the caulking areas for any leaks.

    If you want it to go to a different area before dropping off.
    Just tilt the level higher on the opposite side.
  • They are all designed to dump the water onto the roof like that, and which corner it runs to depends on how the rig is parked. The idea is that the roof is supposed to be waterproof, and condensate will have a chance to evaporate before running off in an out-of-the-way place.

    Where would you like it to drain off to? if the front right is inconvenient, park the rig so that the back left is the low spot. It's gotta go somewhere, but I've never heard of anyone attempting to add a condensate line. Sounds like a lot of work to me.
