Water leak

[Poppy]

I found out I had a water leak that soaked and stained the bed sheet, not to mention doing damage to the night stand.
I thought it was leaking from the overhead ven, so I replaced the vent with a second AC and covers on the other 2 vents.
Today I find there is still a leak.
I’ve never had this much trouble out of 1 trailer befor.
I didn’t bother mentioning problems when I first got it.
But, now what do I do? Do I cover the seams with Coro-last or is there something better?
I just had the AC installed, so my funds this year I will not allow me to have a tech to do the work, so what do you all recommend. The front cap is black, and my wife hates for anything to look tacky.

Gist up there and inspect the roof and front cap, it’s likely the leak is where the front cap meets the roof.I used Dicor self leveling lap sealant
