Proper fix is all above the floor. Helps keep the pipes protected from freezing and other damage. PEX will make things easier once you figure out where you need to run it. It's flexible enough to get most places easily.
City water originally would have come in through a hose spigot near the rear bumper to a pressure regulator then branched from there to the bath and kitchen, feeding the water heater on its way.
