A 500 holds 400 gallons of LP and a 1000 holds 800.We tell every customer about the 30/30 rule before installing their generator. You will get line freezing due to inadequate pressure/condensation formation when the tank is below 30% liquid volume and the temperature is at or below 30 degrees f. In cold weather, you are basically limited to 280 gallons of useful fule in a 500 gallon tank and 560 in a 1000. This is why you often see the old timers warming their LP tank with weed burners are burn barrels. I don't have the balls to do that myself. Get as much volume as you can (i.e. twin 1000's), or look into LP tank heat blankets.</blockquote>
