switching to dual propane

Helped a neighbour with that. Most of what you need will be in stock at either an RV store of homedepot (for the hardware). We used threaded rod etc.

Ours also only came with one but we just decided to carry an emergency 5 pound bottle in case we ever ran out. 12000 kilometres on the road so far this year and haven’t miscalculated yet. :). I just pick up the 20 and give it a shake to see how much is still in there.

Good luck with the project.

Option is a new rack and only connect one tank, when it runs empty manually transfer and re-light any pilots.. (most things other than oven are often DSI now days so that's not often an issue)

Do you actually use a lot of propane? Just curious. My TT has two 30lb tanks, and we've never emptied one of them in one season. But... we only go out usually a couple weekends in the fall, when we mostly use the heater in the TT which gobbles propane.

I use my tt year round, 2 years ago I was going through a bottle a week or better with the trailer being heated to 70F for 8-12 hours a day. Last winter I added a 3rd circuit and with 2.5-3kw of electric heaters I barely went through any. If you're going to use your trailer in the winter up north without electric it's a must IMHO.

This is the switchover valve that I recommend. It is also a regulator, so you don't need your current one. Other than that, you about have it covered.

Cavagna Kosan 924N RV Auto Changeover Regulator w/RV 'L' Bracket.

What is it that you like about the Cavagna? I can see the advantage of one that has a lever to tell it which tank to use first.

1. It is easy to read from any angle. The red that you see in the photo means the selected tank is empty. When you select the full tank, that red turns green. The color is not only visible from the end like the photo shows. The color is also visible from the side, any side.
2. It has a knob to tell it which tank to pull from first rather than a lever. The white ring around the clear section turns with a pointer to point to one tank or the other so you know which tank is selected.
3. I have read a LOT of failure posts about the one with the lever. I have read very few failure posts about this one.

Interesting, one comment on Amazon said that it decides which tank to draw from based on which tank you open first. I like the knob better than that.

Great, then go buy one. This is like a 1 hour 1 beer project

Yes. But. If you open the tank that the regulator is NOT pointing at, the regulator will show red, meaning no propane at the tank pointed at, but propane will be drawn from the open tank. When you, then, open the second tank (the one pointed at) the regulator will turn green, meaning it is getting propane from THAT tank. If both tanks have propane, and both tanks are open, and the regulator is green, it is drawing from the tank that is pointed at.

In other words, that commenter has no idea how it works.

Um NO. There is a pointer and that will be the primary cylinder that empties first.

Very possible the amazon person is clueless.

Not seen in the pictures as it is behind pointing at the left side.
