Two propane bottles are better than one but they are still a pain in the butt.  How do you know if they are full or not?

Weighing the bottles is very accurate but they are bolted to the camper tongue and I don't carry a scale.  (16 lbs empty, 36 lbs full)

Boiling water and pouring it on the side of the tanks works but takes a long time and is a hassle.

This gauge is junk.  Your bottle is filled with liquid propane and propane gas fills the remainder of the bottle.  If you bottle is 80% full or 40% full, it has the same gas pressure so the gauge only reads accurate at full or empty.

These fiberglass tanks are easy to see through but cost 5-10x as much to purchase and have had several recalls.  They also need to be inspected every 7 years and can only be inspected once.

Worthington makes a propane tank with a built in gauge.  The gauge is attached to a float inside the tank (like the gas tank in a vehicle)  It is reasonably priced and accurate.  I've heard towing with an empty tank can screw up the float.

Regardless of the tank you choose, here is another option for knowing whats going on with the propane tanks.  It's the Marshall Gas Controls RCI-24 Remote Changeover Indicator.  When one propane tank is empty and automatically changes to the other, an LED light comes on in the camper and give you a heads up.  You do need to use the Marshall Changeover Regulator if you don't already have one.

I've used the Marshal auto changeover and remote indicator on 4 different campers over the past 25+ years.
It's a great product and dates back to around the 1960's when I first saw one.
It's my understanding that they've been discontinued and are no longer in production.
Marshal was the only manufacturer that made this type of remote indicator to my knowledge.
So if you want an auto switchover with remote, I'd get them before they are all gone.

Typical autochange features won't work for my setup. I have a high pressure exterior stove. The dual tanks go thru the HP regulator, tee to stove, than LP regulator to rest of camper. I would love an auto change that was not part of a regulator.

The fiberglass tanks that are available now haven't had any recalls-the other company went bust. If they weren't so ridiculously expensive in Korea I'd use them!
