Your post was well-stated.
And the replies equally balanced.
I'm like yourself; a numbers guy.
And would take #2 Adventurer for the following reason:
Floor plan is more important - but "newer" does have more value and will show up in resale or insurance replacement.
(Plus, "newer" has another hidden feature due to the recent recession. Many lost their jobs. . .the best stayed on or were snatched up by other companies. A newer camper is statistically more likely to have been built by someone who cares.)
So they are of equal value in my decision tree.
I'd go with the numbers.
