Have you checked out RVT.com
http://www.rvt.com/Holiday-Rambler-N...424114-UX21263
There are quite a few Holiday Rambler 04's listed there to give you an idea on worth and features. In general those units are very well equipped and are very nice units.
We have been RV'rs for many years and own a Class A.
Feel free to PM me if you'd like to chat.
Happy trails :-)
