This is our 2003 E150 with a Regency Conversion.
The van came with a 5.4L V8, limited slip and towing package. The conversion brought a 23 inch flat panel TV, surround sound, DVD, game console and VCP. I added the wheels, graphics, notebook based entertainment/navigation and a network access server (NAS).
The NAS has 7.4TB of storage for all our movies, music, pictures, etc. It also handles the computer network in the van.
We take this thing all over the country. It's our rolling family room.
