I ended up with my 05 dynasty after spending quite a bit of time trying to buy an 04 dynasty. The interior height was significant and my 05 has the remote controlled Girard electric awnings for patio and entry door. Seems like I remember something about the TV cabinet between the driver and passenger sticking out quite a bit more on the 04. I also ended up with the residential refrigerator option (not sure if available in 04) Also, I think the "alladin" system was standard in the 05 and not in the 04. Air leveling option would be something to look at. Hopefully someone with an 04 dynasty will chime in and let us know. Here is the location with specs for both. Monaco Coach - brochures
(the 04 brochure is not listed but I think it is the same as the 03).
