Camper Door Tough to close 190

About to take my new 190 out again for the second trip. We have notified that it seems like an excessive amount of force is needed to complete close the front/screen door. I really have to put my weight onto the latch for it to catch. Is this common? Also the screen door doesn’t seem to want to easily separate from the main door. Am I doing something wrong or are there adjustments that can be made?

+1 what StephenH said. Make sure to keep it lubricated, I know it sounds weird to lube a friction hinge. Continuing to force the door will twist the door frame. The door frames are very thin and will torque and separate from the inner door panel. And one more thing to add to the to-do list, make sure the screws on the lock and latch mechanism are tight as well. It will begin to "float" in the door panel and make opening and closing difficult. I have to tighten ours every few trips.

I’ll have to give that lube a try. Also, It doesn’t seem to open any different while level and the stabilizer jacks up vs having the jacks down. 

I didn’t even consider that.

I have made a modification to the striker plate on the door frame and seem to have made a big difference. Also without the striker plate the door opens smoothly and closes without ease. But the door frame is just some thin metal and I can’t see it holding up long without a solid steel striker plate attached to the door.
