Former Boater has it pretty much on the money as far as fundamental differences in those years. Any other differences will depend on how many options the Dream has - there are some that are sometimes called "Dreagles" - a Dream that has been optioned to be very close to an Eagle. A friend has a 2000 Dream that even has the heated tile floor, which is an option even on an Eagle.
You can download 2000 Dream and Eagle brochures from the American Coach website.

If they don't still have the Dream brochures online, I can email you a 2000 Dream brochure in pdf format.
