I looked at a 2004 here in Denver and it was TOTALLY trached. Kind of sad to see. Reinforcing my attraction to the solid fiberglass units. I bought a 2005 Bigfoot that had been totally ignored and it was still in good shape, no leaks, needed some elbow grease an a new front decal (and a new water heater as they old one had froze and split.
Moral is that the conventional stick built campers are very sensitive to upkeep and maintenance so make sure you inspect them WELL, before purchase. A small leak can mean major rot damage.
That said I think the Okanagan unit are a good choice if you can find one well maintained.
