What all does it take to run 2 bottles?
All I did was remove one line and added a y-block, to save weight, less chance of leak ect. I have 10 bottles already, so it didn't cost me much. I had to buy 1 more heater.
You will need two sets of bootle brackets, Two bottles, a Y connector and two hoses to go from the Y to the bottles.
I suggest dual heater elements. You can use one pressure switch.
