Hey, everyone with entry door issues!
Early in our ownership of our 2023 310RL we thought we had a faulty door. It would stick when we tried to open it, and it would bind when closing, sometimes just bouncing open without latching. It sounded like everyone else's problems. No, it never flew open while driving, thankfully! When I looked it over, I found that one, yes ONE screw head on the door was touching the frame when closed. I replaced the round head screw with a flat head countersunk into the edge of the door and the problem was solved.
Moral of the story- look for the easy stuff first. It's easy to get wrapped up in the "problem of the month" that is so common on brand or model-specific forums. I have a Power Wagon, and I had so many catastrophic issues until I realized I didn't always experience everything I read. I hope this makes sense.
