This style camper hatch may put you in trouble for rot:

Follow-up to our camper rot / water infil issues:

Just a heads-up to anyone owning a truck camper with exterior hatches (I suspect that this would be everyone with a camper):

-the style of hatch in the photo (this is ours to the propane containment) may be a persistent leaker when you have rains:



This is the hatch (and, our battery hatch: same style) that allowed water to leak into our Outfitter; water infil that nearly destroyed our camper.

History: I tried every mitigation I could devise (drilling holes at bottom of hatch door; placing a new rubber gasket; blocking the vent slots (not a good idea, but in desperation, I had to try it), re-seating and caulking the entire perimeter of the radius frames FROM THE INSIDE OF THE CONTAINMENT COMPARTMENT; and numerous other ideas, like canting camper to the propane hatch side and battery hatch side; etc, etc, etc, etc, etc, etc) and NOTHING I implemented will keep water out of my propane compartment or battery compartment. They flood inside compartments at every rain lasting more than about 45 minutes. Just this morning, I shoveled half an inch of rain water out of my large propane compartment (THANK GOD I had sealed all the seams of my battery and propane compartment containment containers, turning them nto swimming pools, or all my work removing rotted wood from and repairing this camper would have been for not !).

WATCH OUT and PAY ATTENTION to what hatch frame and door system you get on your new purchase, and do some serious investigating into your current hatch doors (all of them), or you could lose your camper to extensive water leaking and resultant catastrophic rot.

The problem appears to be:

1) door frame filling with water and over-spilling into compartment at bottom (drilling holes in door frame does not work effectively!);

2) the long/large hatch hinge extremely poorly designed, allows water to pour into the compartments (absolutely no mitigation possible on this frame hinge design!).

I have been relegated to tarping both hatches permanently (both when camper is in the immobile state in driveway AND camping). And, I pack huge bath towels into the compartments when driving if encountering rain.

    Our propane hatch has the double-cut bottom flange (I think the manufacturer of the hatch cuts these, not Outfitter?). The first thing did was dam the 2 cut-outs, with 3M closed-cell foam strips, backed by house-wrap tape (this tape is indestructible by weather/water).

    This did absolutely nothing against water infil. It actually made the problem worse. Then, I drilled 2 large weeping holes along bottom of hinged door (water poured out of the door frame onto my expensive Bosche drill when I pierced the 1st hole!). 2 holes did nothing WITH the foam dams in place. Took dams off, still water came in. Note: the hinged door frame with rubber spacer is HIGHER than the mating frame-stopper (the mating frame-stopper has that built in rubber gasket, but think about it: f the door weeping holes do not drain the frame filling water quick enough, the water will overspill totally over the frame flange into the compartment VERY EFFICIENTLY :E ).

    Then, drilled 3 holes in the bottom of door; useless. Water still coming in. I then put an after-market gasket all around the radius door frame. This did nothing to stop the water infil. Then, I sealed all the horizontal air vents in the hatch door: no good. Still water pouring in. Hey Zeus...what the h*ll do I do next? I inspect the hatch door hinges, and caulk the end flanges (2 on each hatch door). Nada. Water pouring in. Now I'm getting really pi**ed off. I examine the door hinges and visually reverse-engineer them.....these hinges are actually PERFECT eaves troughs, effectively funneling water INTO the containment compartments (whether they are top mounted or side mounted, doesn't make a hill of beans of difference how they are mounted)! Jeez. So, I now cant the camper towards the rear and propane door side slightly (taking advantage of rain shielding and roof drip)..I almost forgot: I also caulked all around the exterior door panels where they mate to door frame early on..then:

    .....so, I pack large bath towels in both compartments lining the floors, and trim large sheets of vapor barrier (clear poly 8mm thick) over both hatches permanently (I now carry these poly tarps and a roll of house wrap tape with me at all times in camper in case of rain!)...

    I'm now interested in tearing this******out of the walls of the camper and installing some yet-to-be-discovered vastly superior hatch door system.
  • Silver,

    Have you found the problem happening in all of the exterior doors or just the ones that Outfitter cut the bottom lip off? Seems like that would be a lot of the problem.
  • I am sure there are thousands of doors this style. Nice documentation. RV manufacturer's are you seeing this? Do you care?
  • ....one thing I forgot to mention: early on when I 1st found water in the battery and propane containment canisters, I thought about why I had not ever seen water in these places before.

    I came to the conclusion that a) we were only camping ~3 times a season max since 2010, so never had a need to look in/open the hatch but for 3 times a year; b) the water that was flooding in probably drained right into the camper structure and disappeared perhaps over a week or two.

    So, a thought would be: even though we may not find water in these containment centers today, water could be getting in there during rains, draining quickly into your camper structure, and the left over film of water on canister floor is drying very rapidly (between rains)....hmmmm?
  • Hi Guys:

    Bob: watering systems blast water almost straight up; that I'd be worried about :B

    Woodhog:

    Nice work. I've thought about re-bedding some of the exterior fixtures using windshield mounting butyl, however, worry about removing the fixture when the housing would need to be replaced.

    The RV caulking strips seem to dry out too quickly, because the rolls they come in have exposed edges when factory packed.

    I would love to find high quality properly designed RV hatches and radius frames that will directly fit the current frame-ins in our camper walls. Anyone have any names, part numbers, anecdotes ?
  • Thanks for posting! It made me go and and check mine. AF seems to have a pretty decent set up. There are no holes or stanchions on the bottom to allow water to seep out. Just the front seam where the plastic bin meets up with the TC framing. That appears to be sealed pretty good, but still an area to keep an eye on. Im going to run another bead of silicone along mainly the bottom just to make sure.
  • Sorry to see that on your camper, just another example of how it is almost impossible to keep the water out of these things.

    I have been removing all exterior fittings, anything that is sealed with a caulking gun, rebedding in Butyl tape, remounting and then caulking again.

    If I ever buy another TC it will have no wood...
  • Hi Silver , hope all is well .
    Tnx. for the heads up it's helpful to me , I have the same set up with my horizontal tanks. Nice job on illustrating. I should show this to my neighbor who insists that my TC needs watering as her lawn does.

  • Being you tried all kinds of fixes, time to get hatch that water can't get into.
