newbie with a t2370!

Hi I just bought my 2000 camper which I believe is a t2370.its in really good shape but for one problem.the refrigerator door broke at the bottom hinge. Unfortunately, dometic discontinued the door. Its from an rm2652.if anyone knows where I can find another door,that would be great!
Otherwise I'm really impressed with the quality of the construction especially the cabinetry.
Another question I have is About the roof. should there be a space between the outer roof And the inner?
Thanks All Happy Camping!
