Well, I'm in "Small Town USA".
LPG deliveries are 3 days max. Mostly 2nd day. A few are same day.

I would do the auto-fill thing, but I only have a 250 gallon tank and only cook and sometimes heat with gas.
A 100 gallon order in May will normally last until October.
Not only would a stop be almost silly for 5 to 10 gallons, I don't want the gas company hitting my bank account unless I know about it. Blame it on my OFS! LOL!
