Some are just Excellas, and then some are labeled "Excella Classic" like our 1992 29'. Our Excella Classic has parquet floor in the living room and
area (original). Lots of little extras in the trim, but not a lot of difference. Beautiful engraved mirrored cabinets on the entertainment center in the classic model, mirrored closet doors, doorbell, etc.
We bought one recently that is just an "Excella" - 1987. It has the tambor- or whatever they call them - sliding up cabinet covers on both ends, but is oak otherwise. Our Excella Classic has all oak cabinetry. The Excella is a little plainer in our opinion.
Both our trailers have OSB. If it's kept dry, no problem. If there are rotten spots not too big, you can patch. If there are tiny wet or soft spots, fill 'em up with that Rid Rot, or Git Rot, or whatever that epoxy stuff is. On our little spot by the door (most all old ones have it) we filled it up with epoxy...it's hard as a rock. We replaced half the back floor on the curbside because a gasket seal had failed on the storage compartment and it had gotten wet. (pretty common) The rest is fine.
Don't get scared. You bought a great trailer! We've hauled our 1992 over 25,000 miles. She has never faltered. We worried so much when we first bought ours we couldn't enjoy it. Just enjoy! Fix and fix up as you want, but USE it, and you'll be happy!
