Sink Drawer Install
One of the "motorhome" qualifications is a water supply with a sink. BillR (Bill) added a sink to a drawer in his Volvo VNL770.
Sink in a Drawer is a set of photos of the installtion steps.
The Sink is a Stainless mixing bowl from Walmart and pump is a Shurflow 12V elec faucet/pump combo from ebay. Water drains out overboard. I used a 2.5 gal plastic water jug in the lower storage compartment. The Pump is mounted there.
