Tommy....Typically, coaches come with only two or three. Many times, the show coaches have a lot of options on them so people can see what's available and are wowed by the goodies.
We bought our coach new last year. The basic TV arrangement was one in the bedroom and one in the living room. My dealer likes the one over the dash and the outside unit, so any coach he orders for his lot have four TV's.
We laughed at the number our coach came with, but found the optional TV (40") over the dash was better suited for watching TV when it was just the two of us. When we have company over to watch a show or movie, the TV (46") on a televator is best. We've never had an outside TV, but have found it useful for movie night with the grandkids and sports when the adults are outside.
The funny part, in a year of ownership, we've never turned on the bedroom TV. We're not bedroom TV people. So these coaches are being set up for different life and viewing styles.
