Advice for leaky doors!

Hey guys ,
So we've completed our camper, but have been fighting some struggles with leaking on the doors. We purchased two doors and found that they leaked all throughout the window, which the company resealed and fixed, but then we had some more issues with their seal by the hinges while towing in rain. The company replaced those doors under warranty and just sent us two new doors. The doors seem to be watertight outside of the camper, but when we mounted them last night, we discovered that now they leak in an entirely new spot.
Before we mounted it in the hole, it seems that the door would not sit squarely. It had enough room up and down and side to side in the hole to move , but it didn't sit very flat against the camper(the driver side door did fit flush against the camper in the passenger side opening) . We were hoping that screwing would bring it up flush and not cause any problems. After it was all screwed in, it was very visible that the weatherstripping on the door was pulled away from the frame a little in the upper corner, and there was a gap. Sure enough, when we sprayed for a water test, water leaked in there and down the inside of the door.
Our trailer walls seem square, and it seems strange that the door did not sit right before, but then the other door does seem to sit right. Any suggestions? We were thinking about possibly trying to shim behind corners of the door to bring it flush?
I can add some pictures later today if I need, any help or past experiences would be appreciated!
Thanks!
