There are plenty of solutions posted; however the OP asks why. The reasons are:
A When no furnace being used. With the door closed it is removed from all sources of heat, ie people, appliances, etc. With the door open it is the furthest from those sources.
B With furnace being used. RV duct systems are rarely laid out for the proper heat distribution and the bath ends up without much heat as it is at the end of the run.
C Adding to the above is the fact that the bath has a higher heat loss because the vent (and on newer units skylight) which is covered by a thin piece of plastic with no insulation value is a larger percentage of the ceiling area than the same items in the rest of the RV.
