We should all carry a small, spray bottle of soapy water (dilute dishwashing soap) to check our propane connections. No reason to get rattled, just do the following:
1. Open both propane tanks all the way (some propane valves only seat when they are all the open or all the way closed. Never open half way)
2. Make sure your selector switch is all the way to one tank or the other (some selector switches leak in the middle position)
3. Now, check all the connections with soapy water. Tighten if necessary.
4. On a 2006, I don't believe you have any pilot lights, but if you do, you must either light them or turn them off. Otherwise, they will "leak" propane.
5. On my older Airstreams, I just turned the pilot on the stove top off and used a butane lighter for this very reason.
