Ravenna Habitation Door not closing

The Habitation Door on my Ravenna does not close properly.  It does not seal on the bottom corner away from the hinge.  It is as if the door is twisted.  It locks so not a security problem but I can hear road noise through the gap.  Is there anything that can be done.  Pictures below show the gap when closed.

Hi have you checked the door catches are locating properly and do they need adjustment

Mine is the same, slight gap at bottom corner, did you get anywhere with it?

With the door open try to operate the catches to the closed position then operate the handle do they both latch close and then snap open when you operate the handle. If the bottom catch does not operate the same as the top it is likely that a small 50p spring has snapped on the lock mechanism, preventing the bottom of the door from locking.

It dosn't have top or bottom catches.  The door is warped I think.  I will look at it again in the Spring.

Yes mine just has the centre catch, i had a look at it this morning and adjusted the catch by about 5mm, so it now pulls the door a lot more in, the gap seems to have reduced considerably. I guess flex etc means the door may well  not fix so snugly as when new. Still at least I cant see daylight through now. We are are off this weekend for our first trip of 2018, mind you it was so cold today, I might regret it.
