This is a very slick Sprinter van conversion that finishes with very polished van kitchen and lounge areas, but the key is the electric hoist bed that lowers from a bulkhead in the ceiling to neatly sit over the sofa/storage.
We made the curtains by covering both sides of a silver windcreen sunscreen with material. The rear door ones just sit inside the door frame, and the sliding door one is held by strong magnets. Totally blocks the light.
Three 20L jerry cans under the sink - two for water, one for waste. Drinking water kept in the fridge. Using jerry cans makes refilling /emptying easy. A couple of 12 v pumps get the water to the taps.
There is an internal and an external table. The inside one folds away and is stored in the arm of the sofa. The outside one folds down from the back of the sink cupboard in the door way, for sitting outside.
We use 2x 150 Ah AGM batteries (Ritar brand), wired in parallel. Morningstar Tristar 45 PWM controller. We have a couple of inverters (380 watt pure sine wave, and 1200 watt modified sine wave). It is all monitored using a Trimetric 2025 battery monitor.
475 watts of solar on the roof. They're glued / screwed to two aluminium box frames. 5 panels are wired together in parrallel on the roof, so heavy cable can be run to to the charge controller to minimise voltage drop and subsequent loss of power.
