If you use just one propane tank, you need a regulator designed for one tank. These Marshall 290 Series two-stage regulators are exactly what you need for safe and reliable gas supply on your one-tank system.

A protective cover (sold separately) is recommended and is necessary to meet RVIA requirements for use on RVs.

Choose between Vertical (shown in main photo) or Horizontal (shown under MORE PHOTOS) regulator mounting position.  By specifying, you will ensure that the vent always points down when mounted.  Whether your propane tank is vertical or horizontal does not determine how you mount the regulator.
