We own a 2023 Imagine 2670MK and we've got a leak in the front of the trailer that I was really lucky to find. I'm in the middle of a battery upgrade and I was considering placing the batteries inside the dead space between the front of the trailer and inside of the storage bay. So I pried back the paneling a bit so I could get a better look. When I stuck my hand in to move the insulation back I found the the insulation was soaking wet at the bottom. So I removed the rest of the paneling and found a lot of wet insulation all the way across the trailer. I went up on the roof and didn't find any obvious sources of the leak and everything looked okay. I also examined the seals that run down the sides cap and they seemed okay as well. I also examined the cap where the fiberglass cap joins the aluminum skin (it's coated black). So then I got out the garden hose out to see if I could find it. I hit the seam where the fiberglass cap meets the aluminum and water started to trickle in in a few spots. The water dripped down and hit a square aluminum bar and ran across, where it was absorbed by the insulation. So I called Grand Design and they told me that I was out of warranty. They suggested that I take it to a RV dealer to have it repaired. I told them the closest GD dealer was two hours away and that this looks to be a simple repair and that I'd like to do it myself. Their only advice was to use Geocel 2300 sealant. So I ordered a tube from Amazon and went out today to do the repair. The seem that's leaking has a black metal edge with screws every few inches. My plan was to loosen the screws and inject sealant behind the metal strip. Then tighten the screws back and wipe up the excess. Unfortunately, I don't have a tool that matches the screw head, so I can't loosen the screws. Its not a Torx, or philps head. It looks like a combination between a Torx and an Allen key. Does anyone know what type of screw head this is?
