You are right.
Valmiki Ramayana portrays Rama as a complete human being. Ravana, while asking for his boon gave a big list of creatures that would not cause him death. He left out human beings as he thought that they were not a threat. It was for this reason Lord Vishnu had to incarnate as a human being and not know his own identiy or his divinity till he killed Ravan. After that, it did not matter whether Rama knew who he really was or not. It was for this reason Indra Deva rushed away from a sage's ashram before Rama could see him - if Indra Deva had met Rama in person, he should bow down for he was Lord Vishnu and that would have told everyone that Rama was indeed Lord Vishnu. Hence, till Ravan was destroyed, Rama's real identity had to remain unknown. Though many sages did guess who he really was, they did not reveal it openly.
In Tulsidas Ramayan and many other versions, it is mostly the devotion to the Lord which is highlighted and not the question as to how Rama could manage the feats he could without using his powers. In these versions, the characters recognized who Rama really was and most of them worshipped him.
