I just looked at them. They are standard grill tanks (empty of course). While inspecting them I read all the warning label. One of the warnings is "use in an upright position only". In the mini-Winni they are mounted on their side.
Is there any difference in the valves on the horizontal and vertical tanks?
Can I use these grill tanks? Should I only have them filled 50%?
If the new tanks don't look like these, then NO, do not use them unless you remodel the compartment to properly vertically install the BBQ tanks.
A horizontal RV bottle will look like this:
New, these cost around $150 or so apiece. Trying to use a vertical bottle, will result in liquid propane in the lines vs gas, and a rather ugly fire.
