Superchief was Winnebago's earliest basement/large storage type A motorhome. As you get into later model years, and the other lines were redesigned as basement models, there are more choices.
The Bounder was the equivalent at Fleetwood, and I think in the early '90s they were pretty well thought out, pretty well made. I don't know that there were any Bounders shorter than 30 feet, the ones I saw when shopping 2004-2005 were 32 or 34. Here is a
link to a 1994 Bounder recently sold at PPL for $8000. Most Bounders later than this vintage will have slideouts, and will sell for at least twice as much. The non-slide models are much less expensive because nobody wants them today.
By the late 1990s Fleetwood was making a lower cost basement model line called Southwind Storm that was almost equivalent to the late 1980s Bounders, sized to fit on a 16,000 pound P-series chassis. Also mostly non-slideout, like earlier Bounders, these "Stormy" motorhomes can often be found for about the same price as a Bounder that is ten years older.
I suspect if might be easier to find an early Bounder, or somewhat newer Stormy, than to find a SuperChief. Winnebago did not sell a lot of SuperChief models before incorporating the storage features into the more popular Chieftain (still low profile in 1990).
