TV location and cabinetry typically vary by floor plan, so other '07 Discoverys may differ from yours. Even other brands of other coaches will be similar, though, with just minor differences in details.
Basically the choice is to mount within the existing cabinet or on the face of it (the tv is thin enough that it does not have to be recessed). Mounting on the face allows a larger tv in most cases. You can also decide whether to reduce the depth of the cabinet or leave it as-is.
