In that era B+ type Cs were just growing from a boutique market into something offered by major manufacturers. Before 2000, look for Coachhouse, Dynamax. , Later R-Vision started doing some of their Trail Lite C's without the overhead bed, Gulfstream entered the market with th BT Cruiser, inventing "B+" as a marketing term, Phoenix Cruiser started manufacturing, and Forest River created the Lexington line, stretching the B+ idea to include some very large Cs, up to 30 ft.
When I was shopping in 2004, most of what was pre-2000 used was Coachhouse, what was available new was mostly Gulfstream and Forest River, with Phoenix Cruiser trying to establish a dealer network.
When I look around today at the used market, what I see most are Winnebago Aspect and its Itasca twin, because that's the volume manufacturer that stayed with the type, after others backed out of the segment during the recession. But those will be mostly 2005 and later, and indeed, the B+ market was at it's peak 2005-2008, so you might adjust your target years. 2005-2008 even Coachmen, Thor/Fourwinds and Fleetwood got into the B+ segment.
