2021 Nucamp T@G - Galley Leak

One thing I noticed when it leaked was the parking position. The trailer is parked in a facility with a gravel lot.  Our space is toward the back of the lot on an incline (nose down).  After I discovered the leak and trying to figure out why it had just started, I decided to crank the nose up so the trailer was level.  The facility recently put down fresh gravel so it's possible the incline was a bit steeper than in the past.  We've had a few rains today for about an hour, so I went down to check.  Dry!  I'll hold off on declaring victory until we have a good rain, but this jives with our year of ownership and lots of rainy nights.  Galley is always dry and the trailer is level where we're camping.  

If this is the cause (stern was raised, bow declined).  What would be the points of water entry I would investigate?  It must be a pretty specific leak point to only occur when the bow is declined to a certain angle. 

I've spent some time at the lot investigating.  The seels all seem tight.  On the lower edge with a dollar bill shut in the galley seels, I'm unable to easily pull the dollar out.  I have noticed that when shutting the galley, I can easily close the t-handle.  When we first bought it, we would lean on the door while closing the t-handle and you could feel the drag of the the cam in the post.

I marked the current position of the cam, loosened the hex bolt and slid it a bit further up to pull the hatch in closer as it latches.  We'll see how it it works!

The silver shows where the bottom of the latch was previously.  I also ordered some plastic cam plates to replace the washers.  Originally, each t-handle had one large washer and one tiny washer.  The tiny washer was getting sucked into the hatch.  What does everyone else have here on the back of the t-handle?

Note: I have nylon lock nuts but waiting for the plastic cam plate to arrive.  These washers were a temporary fix.

My 2018 T@G has not experienced any galley leaks so far. No adjustments have been made on the latches.  No modifications. 

Did you add tape to the cam shaft?  I could see that helping to prevent the cam from sliding.

Well, I thought by getting the cam closer to the latch that would pull the galley door tighter on the seals and stop the leak.  Today we had our first good downpour since the adjustment, although the water intrusion was less than previous rains, I still had water in the galley. 



For reference, the water pools where the red triangle is located.  The opposite side is dry.  Opening the door after a heavy rain I find the sill plate (blue line) has standing water.  It seems like that is how the water is getting into the hatch.  I did test the seals in that area with a dollar bill and shut the door.  The dollar does not move easily when pulled meaning the seals are tight. 



When I adjusted the cam and replaced the bolts on the t-handle, I also cut some new gasket from 1/16" neoprene in case the old foam gasket were leaking.  

I believe the repair may be completed.  I reattached the loose weatherstripping on the door with 3M Weatherstripping Adhesive then sealed the bottom edge of the door, where the water channels, with some Sika Pro Select sealant to divert it away from the weatherstripping.



I ran another test and I did not see water in the galley.  I'm awaiting one more good rain before declaring victory.
