I built this van myself 10 years ago, having worked in the motor trade for most of my life.

It has mains hook up,  a 3 way fridge, with large freezer compartment. Hot and cold water which operates on gas and 240v. Central heating which operates on gas and 240v. A full cooker with oven and grill. A double drainer sink.with an onboard grey water tank, separate bathroom with a shower, sink and cassette toilet.  There is also a TV bracket  with connections for both mains and 12v. with an omnidirectional TV arial and power booster. There is a rear lounge, which converts into a double bed, plus a seperate dining area, which converts into a single bed, and a captains chair in the front passenger side. There are lots of overhead storage boxes, plus storage under the bunks and over the cab.
