Battery Compartment Door Leak

[McDonalds]

Recently, I replaced the rubber gasket around my battery door in hopes that was all I needed to stop a pesky leak. Unfortunately, it didn't stop it. I realized that the compartment door is sprung, just a little. When I push on the right side of the door, the close is complete. Anyone have any ideas about how to fix this problem? It just needs something to exert a little pressure to keep it pushed in.
Thanks!

If it's like the hold on my '69TW, there's a small screw that adjusts the position on the latch.

Loosen the screw and move the latch closer to the backside of the door—this will give you a tighter close.

That's an excellent idea! I didn't know if the latch had an adjustment. As a last resort, I was going to add a strip of garage door rubber over the crack between the trailer and the door. It is either that or adding a twist stop to exert pressure to the door for a tighter seal. I hope your suggestion works. Thanks.

And in the interim, I recommend Aluminum Tape to seal things up—it's my new best friend!

Went looking for the latch adjustment and there was none. There was just a nut to keep the latch in place, no adjustment screw. I was thinking about putting another round of gasket in the location of the leak, but then the door might be too tight, producing a leak elsewhere. ??????
