I recently bought this series on DVD (also many entries on my overalls blog, f/m). Somehow I was a bit disappointed and expected more episode with kids.
Pic 1 is from s3e19 (1987) about 2 boys, one blond and one darkhaired, around 11 yo. Obviously these brothers sharing these interesting room and one double bed (not shown sleeping though). There are also 2 other brothers shown.
Pic 2 is from s3e9 (1986) showing a University dorm with a young men sharing the room with a 12 yo student. He even asked the older roommate if he mind that he’s only 12 yo. Handsome Jeff Bryan Davis and good plot but no sleeping shown as well.
For more episodes, also involving bunk beds and summer camp dorms, see the main entry rating 6
