We own a 2004 Safari Zanzibar 40-foot diesel pusher. As with all coaches of this age we have analog televisions in the front and in the bedroom. I am considering switching to HD (flat 1080). How difficult is this to do and can it be done by a reasonably adept handyman? Also has anyone updated to a Front Projector System. My present configuration is the normal mounting, high between driver and passenger. If I go with the Front Pojector I plan on placing the Projector wher the TV is now located. I appreciate your comments and help.
