The drain plug is only to keep bugs out... Not needed really IMO
Apparently Dometic doesn't agree. From Page 23 of this Dometic Diagnostic Service Manual that plug is actually a check valve that serves a very important function ...
"Another source for an air leaks could be the drain hose.
When units are installed, there is a check valve at the end
of the drain. At install the hose might be shortened and
the check valve must be moved to the end of drain hose.
Any time lack of performance or excessive frost is experienced, look for the check valve at the end of hose."
Manual says nothing about looping the drain hose. ;)
