Recently we were hitching up to bug out on a week "get outta town"
trip and I knew I had an empty 20 lb LP tank on the trailer.
I -thought- I had a full one in the garage..... wrong!
Now I've got 2 empty tanks and it's Saturday afternoon.
Called around and found a LP filling station at a U-haul major truck
On the phone they said it would run around $19 "depending" because
they charge by the gallon.
When they filled them the guy said most tanks are not empty and usually
hold about 4 galloons.
My tanks held 5 gallons and the bill was $24 per tank
Found out later upon my return there was a Walgreens 2 miles from me
that has a tank trade cage out back and they were trading empty for
full tanks for $18.
I have painted my tanks and they are a "matched set" so I hate to trade
them in but I could have saved $12 and a significant drive in Saturday
afternoon traffic down a major busy highway.
What did you pay the last time you bought LP ??
