2003 Forest River Cardinal 29DSO - looking for info

I'm thinking about buying a 2003 Forest River Cardinal, with the 29DSO floor plan. However, I'm having trouble finding information on it. I can't find it on nadaguides.com or any of the other bluebook sites.

Has anyone heard of it before? Is it a quality unit? I've heard good things about Cardinals but would like to get some hard facts before I buy.

The VIN is 4X4FCAE254G081571 if that helps.

Thanks for the input!
