I bought a brand new Forester MBS 2401W in December for $79,900. It was on the other coast but was $12,000 less than dealers in my state. For $12,000 I said "I'm on my way!"
The dealer in my town only sells trailers but has been quite responsive to my warranty issues (LP regulator didn't work with temp in the 30's, it leaked a little rain due to torn slide seal, etc). He fixed everything without complaint.
The deals are out there for $80k, you just have to keep looking and either be willing to travel, or use that price as leverage in your area.
If you are willing to travel, I actually sent a request for quote to about a dozen random dealers all over America. About half of them responded including the $80k dealer. The deals are out there if you dig hard enough!
For those who don't know, the "W" model is the most expensive Mercedes Benz Sprinter (MBS) model due to it's full side slide which we love! It affords a walk around queen bed, bigger bathroom, etc in a 25' motor home with a turbo diesel V-6.
