What door you buy depends on what your coach was originally cut for (Suburban vs Atwood/Dometic opening):

If you had a 6-gallon Suburban retrofit door/flange:

Black: 2GWHDA6B
White: 2GWHDA6

If you had a 10-gallon Atwood or Suburban retrofit door/flange:

White: 2GWHDAS10

If you 6-gallon Atwood/Dometic retrofit door/flange (paintable to match coach):
