Hi Folks: It appears they would carry some gear on the back deck, but no much. And it appears crews were wearing M1943 clothing just like the infantry. And the football style helmets were still common. Bob
As far as the stowage - remember that an M4A3 takes in its radiator cooling air from on top of the deck, so in WW2 or Korea you see the stowage piled further aft on an M4a3. The M4/M4A1 had a different air handling vent which left more open space on the rear deck, so they had more gear piled there (as long as it didn't interfere with turret traverse).
Korean War M4A3s seem to have operated "closer to home" and one doesn't see as many big piles of personal gear or fuel and lube cans. One does tend to see quite a bit of .30 cal MG ammo stowed on fenders or glacis.
