I live in an area where it is the norm to live off the grid and many people run there houses off of a propane generator and lots of fuel companies in the Green Rush up here in Northern cali are glad to make a buck. However the option of being able to fill your tank at will is an extreme advantage to diesel that I had not thought of. Pretty much sells me on the diesel. Prolly no big deal if you run a clean show, but some folks up here dont and i read a lot lately about fines that are being stuck on people for environmental contamination when Jonny law comes down on um. good stuff thanks much
