My 2002 Southwind (also by Fleetwood) has velcro (yes, I said VELCRO!)across the top of the dash above the instrument cluster where it joins the flat top of the dash, and two screws at the bottom slides. Work your finger under the velcro to pull it apart and the front of the dash will rotate down on the two screws far enough to get the cluster out.
By the way, I replaced the velcro with new industrial strength velcro and it quietened down the squeaks and groans that come from all Fleetwood dashes.
