Rear TV replacement

[JBroadaway]

I am going to replace the analog tv in my bedroom with a digital model. I have a 2005 Itasca Meridian 39K. The tv is located on the passenger side next to the wardrobe closet. It has a movable mount which swings out for better viewing while laying in bed. Has anyone changed the tv in this situation? I've looked at it when swung out and it looks like the three bolts on the bottom are all that is need to remove the old tv. I would like suggestions on how to install an LED/LCD. The area is 21 1/2" wide by 18" high. Most tv's I have looked at range from 19" to 23" screens that meet the width requirements. All tv's I've looked at range in height from 13" to 14 1/2" so I am planning on building a shelf to hold my dvd and directv receiver. Any suggestions will be appreaciated...
