20lb tanks vs 30lb tanks?

Both of the 30lb propane tanks that came with my trailer are expired and I expect to run them empty this season.



I had planned to replace them with new tanks, (one still has the old style valve) but was thinking about buying 20lb tanks instead. We don't heat with propane because the furnace is 37 years old and I don't trust it. We only use the onboard tanks for the fridge and water heater, and only when we don't have electric hook ups. In an average season we go through one 30lb tank and use the other one only until the primary tank is refilled, that's how we managed to keep the tank with the old style valve so long.
2 20lb tanks Should be enough to get us through the summer.


The pros are: 20lb lighter tong weight, lighter tanks to carry to the refill station, 20lb tanks can be exchanged if a refill station is not available, and slightly less cost to buy the new tanks.


I can think of no cons other than the decreased capacity, which is not an issue for us.


Is there any reason not to change to the 20lb tanks?

I don't see a reason. If your 30lb tanks are original to your 37 year old trailer then they may be aluminum and maybe someone on the forums could use them as part of a restoration project to polish up. If they are steel then forget that idea.

If you have the original tanks, they are aluminum and only the valves need to be replaced. An empty 30 lb aluminum tank is lighter that an empty 20 lb steel tank. The aluminum tanks don't rust and will not need to be replaced periodically like a steel tank. Refilling the tanks is substantially cheaper than the replacement tanks.

Plus the aluminum tanks can be polished and they they look fantastic.

Personally I would keep the 30lb aluminum if that's what you have, but it sounds like you are interested in being able to exchange your 20lb tanks for a filled one on the rare occasion one goes empty.

The current tanks are steel, I would love a set of polished aluminum tanks but it's not in the budget right now.
