Yeah, even that forum has technical orientation, we can't get members to understand difference.
TANK is something welded, or bolted to RV frame, or bolted to foundation in front of your house.
Anything you can pull out is CYLINDER.

Most campers will have DOT CYLINDERS , BE they vertical or horizontal and have to be recertified . The weight of an ASME tank is more than twice that of a DOT cylinder of the same size .Kayteg1 wrote:
I ask propane seller in Las Vegas and they directed me to American Gas for re-certification.
The horizontal cylinders with gauge I have sell for about $300 new, so recert is worth it, even doing it last time in California, I paid $25 if not more.
To my understanding, most upright tanks are under DOT regulations and have an expiration date on them, usually every 10 years before re-certification is required.
Horizontal tanks are regulated under ASME guidelines and normally have no certification expiration date.
I believe the difference goes back to how the tank was manufactured, meaning DOT require less 'thickness' of the tank metal while ASME tanks are built with thicker metal, thus fall under different guidelines.
Someone with more experience than I will chime in, so stand by for more information.

Those proclaiming for tank exchange, most (all?) exchanges only fill the tank with 16 lbs of propane. 20% less than filling your own tank
But than few minutes exchange beats 1/2 hr wait for cylinders fill.
My last fill at Costco gave me good price, but was pretty big hassle.
Could not park close to propane pump, so having 2 cylinders had to find a cart and roll it to the center.
Than had to push the bell and wait for attendant. Took several minutes and he filled 2 cylinders, giving me a receipt to pay inside warehouse.
Long waiting lines, even I combined it with grocery pickup, but when i come back with paid receipt, turn out that the paper the attendant gave me had 2 bills on single slip of paper, so had to go back to cashier and pay for the 2nd. .
I have custom cylinders, so exchange for me is not possible, but than having gauge on them, very often leave the 2nd at home.
Not much need to carry spare when it last for 5 or more weeks and the gained storage is good for charcoal and snorkeling gear.

1 more observation.
When you take your cylinders to gas station who also sells propane as side business - they never take a look at certifications.
Done it 4 times in last year.
Never. Except when they do. My tanks have been checked every place I've ever taken them including gas stations selling propane. Expired date, they ask me to move along as they do not cert. Which is how I discovered my local RV parts/repair shop sells propane cheaper than anyone else and certs for $5.

The 20# cylinders in our Bigfoot were in great shape but the expiration date stamp had passed. I contacted numerous local propane dealers and none did recertification. I could not get the cylinders refilled due to expiration date. I ended up buying new cylinders. Check the date on the new ones also,some were already a year old!
