Having a standard model Scamp there is very little area to mount a TV. I added mine by using a pole mount I found on Amazon.
I bought two sets of closet rod ends and a piece of pvc pipe. I cut the pvc to length and mounted it to the cabinets using the closet rod ends. The result is a very sturdy mount that can be rotated to be seen from the dinette or the front bunks.
When travelling the TV is bungied to the cabinet supports.
