Hi, I just bought a van and have spent some 60+ hours researching. Trying to settle on a layout before getting into the details of every inch. Need space for a bike or two, and also need space for mobile offices. Thinking of converting part of the raised bed into a workstation, and using the swivel seat as another station. The annoying thing here is the location of the toilet, which seems a bit inconvenient as a seat. Thinking propane system up the right, electric up the left. Anyone put propane+gray water beneath sink/counter?
