The Minuet was in production from 1977 to 1979. Three models were made. A 6.0 , 6.7 and 7.3
To the best of my knowledge all years and models had aluminum cabinets. As far as the aluminum subfloor all 6.0ís had them, some 6.7ís and few if any 7.3ís.
If the original carpet is still there it does not go under the dinette seats or the lounge.
The subfloor is a foam sheet sandwiched between sheets of aluminum. The aluminum was painted white.
Also like mentioned in posts above the furnace is located under the oven. The refrigerator exterior access door should expose the floor.
Judging a person does not define who they are, it defines who YOU are.
