Horizontal 20 lb. propane tanks.
Okay, now I'm confused. I just got an email ad from a particular RV vendor and they are selling horizontal 20 lb. propane tanks for $157. What is the deal and why would they be so much more expensive ...

Feel free to call a cylinder a tank when the context makes it clear what you're referring to. But, the OP didn't provide any context, and there are a lot of differences between them. $157 is a great price for a tank, it's a decent price for a cylinder.
These are generalizations, there may be occasional exceptions.
ASME tanks are made of heavier gauge material, are intended to be mounted permanently, don't need regular recertification, have fixed supply connections with hard line, are refilled while on the vehicle through a special refill port, and aren't required to have an Overfill Prevention Device (OPD).
DOT cylinders are portable, need recertification every 10 years, some places may require that they be removed from the vehicle before filling, have ACME valve ports with OPD where flexible hose connections are made by hand, and are refilled through the same port.
