I would guess the door was purposely removed since the ladder made it inoperable. The rear fender looks to have been modified for mounting the water pipe.
The late 40s early 50s half tons were produced in fewer numbers than the F2-3 3/4 tons, but more survive since the 3/4 tons were beat to death. I was shocked to only find 2 cracks, both in crossmembers on my 52 F3. I know others who had frames cracked so bad they were beyond salvage.
