Colonial and Airstream NW dealers were particularly helpful to us.
I agree, push the sales people to provide answers. Caveat emptor: dealer installed options can be sinfully over priced.
Do some research before you agree to a price. The solar panel on my AS was originally priced at more than twice
what the local market was asking for the exact same system. The dealer installed it at local market price.
Don't be afraid to negotiate aggressively.
