Propane Installation - Hose Run Questions

Need to install in my 28 foot BCC an aluminum 10 gal horizontal Propane Tank in my starboard mounted deck box which sits next to my mast which would fuel a P9000 Dickinson Marine Newport Heater which would be mounted on the starboard shelf at the foot of my bunk. Additionally, need to install a Force 10 (2 burner) European Compact stove in my galley on the port side aft near my companionway. Need advice on how others have done this, did you run two propane lines down the mast or ? Any input would be greatly appreciated. Armand and Kym on S/V KELSEA
