An Allroad would be great but in your price rage the risk of a turbo going out during the trip is too high.
How about a Forester?
The A/S8 would be great as long as you are not headed too far offroad.
A Cherokee or Grand Cherokee would not be too bad.
A Eurovan might be nice. One trip from Denver To Philly I was quite envious of a Westy driver who was napping at the same rest stop were I was trying to find room to nap in my Coupe.
