Nice job. Is the sofa recovered or new install? Tile? ceramic or vinyl with a grout? The backsplash looks awesome.
We have a similar front tv setup, but with original to the right over passenger, our solution is low tech, but we store the TV in bedroom while travelling, and set on dash for viewing. Converted the TV 'cave' into the component cabinet. 2 sat receivers, surround sound, a-d converter, switches etc.
Saved the space an entertainment center takes up in your conversion, I like that spot for my computer station.
