To Doug Allman,
To answer your question, no, the Marquis and Contessa were not the only models made in the 1980s or 1990s.
Probably the easiest way to see what was made each year is to go to the NADA book, older recreation vehicle appraisal guide, and look at each year.
While production numbers are not given, what is given are model choices, lengths, layout choices and original retail prices.
For example in 1993 under the original company,
Most expensive (approx $360,000) was the Grand Marquis in layouts of brunswick, custom, excelsior, florentine, jubilee, orlov, regent, tiffany
Then Marquis (approx $337,000) was the Marquis in brunswick, excelsior, florentine, jubilee, orlov, regent, tiffany
Next was the Contessa (approx $270 000 to $295,000) in coronet, savoy, calesse, signet, brittany, normandy, orleans
Next the Baronet (approx $190,000 to $198 000) in ormond, rothesay, windsor, chelsea, somerset
Entry level the Patriot (approx $162,000 to $193,000) in charleston, savannah, concord, saratoga, trenton, lexington
Just the next year (1994) with the take over by SMC after the bankruptcy,
Most expensive was the Grand Marquis ($375,000 to $380,000) in layouts of custom, cypress, fraser, rushmore, sedona, sierra.
Then the Marquis (approx $304,000 to $365,000) in cascade, columbia, cypress, fraser, rushmore, sedona. sierra
Next was the Acclaim, SMC's version of the Contessa with a bus front, (approx $272,000 to $280,000) in logan, rainier, whitney, everest, mckinley
Entry level the Patriot (approx $168,000 to $198,000) in charleston, savannah, concord, saratoga, trenton, lexington
Each year had a variety of model choices and layout choices.
And as you can see by the prices, Beavers were very definitely expensive and were considered among the high line coaches.
Hope this helps,
