Hi all,
In one of the trip reports I mentioned that I was having problems with the front bed end allowing water to enter the top of the bed while travelling in the rain.
Well I am trying to gather the information required to see what changes I need to make. I believe that this is an appropriate thread to add to.
I first wanted to work out how the sealing works and then what can be done to fix it or make it better.
Hopefully the wisdom of this forum can help and provide some advice. Any comments will be greatly appreciated especially those that have solved this issue or have modified the hard lids.
So how I think Jayco wants the seal to work is that the hard lid provides a seal via the following items:
1. Top Hinge (sealed to the caravan and lid and having an interlocking track).
2. Rubber seal attached to the inside of the hard lid on three sides (bottom & 2 sides).
3. Rubber seals in top corners to join the two seals above together.
From what I can deduce this is it for sealing. The bed base when folded contacts the sides but does not have a seal and is open at the top by at least 150 mm.
The picture HardLid_001.pdf shows the rubber seal (2) along the bottom, HardLid_002.pdf shows the hinge (1) and the seal in the top corner. Hardlid_003.pdf shows another view of the corner seal with the lid open.

So that may be how it is suppose to work, but I think there is a problem, which can be seen in the photo HardLid_004.pdf. Because Jayco retain the lid in place in the hinge by two self taping screws (one each end), this means that the hinge on the lid is shorter then the hinge on the van. The corner seal is not able to seal a hole between the two.

My theory is that water is leaking through this hole and running along the top of the lid and then falling down on the top of the bed canvas while driving in the rain. Due to all the vents in the van, I assume that there is also a draft that is created to help the water flow in. Amount of water was about two litres over 10 hours (just over 3ml a minute).
I believe that hinge sealant is applied correctly as there is no issue when the van is set-up and it is raining (no water entering from the top).
My thinking of a solution is to remove the corner seal and use the same stuff, but attach it to the top of the hard lid (all the way across) and down the sides at least below the gap in the base and the top.
You may also notice that the hard lid is cracked in the corner and possibly along the edge. This seems to be on both sides, I need to have a look at this and may need to remove the lid to have it repaired.
The other areas that concerned me (more with dust then water) was the the latches and lower corners.
The latch plate is recessed but does not completely fill the hole. This means that the seal is not in contact with anything and that there is a 4 holes along the bottom for dust to enter. This can be seen by the dust and water marks in HardLid_001.pdf (around the lid and latch) and HardLid_005.pdf (around the recess and plate).

I would consider filling the gaps with a hard filler, adding extensions to the latch and then sealing or replacing the latch with a longer one and sealing. Hard filler option the most likely if I can get one in white.
The lower corners seem to be very close to the bed recess (see HardLid_006.pdf). The arc of the lid is too large and needs to be more sharper. It would seem that removing the seal and then making the corner radius smaller and then refitting the seal would correct this problem.
