MJo, when we first picked up our 2020 Scamp
at Backus, the door was very hard to close. We figured it was just because the gasket was new and plump. After a couple of weeks of camping, pushing the door almost closed and then giving it a sharp nudge to latch it, it started to close easier and easier.
I must say though that we never had any trouble opening it, just closing it. So maybe your issue is not the same.
