Trying to "gas us"?

[Braveheart]

A carbon monoxide detector would put your mind at rest somewhat.

We already have one and I tested it before we left UK. After your comment I decided to test it again. It worked fine, however the battery compartment cover fell off to reveal a corroded battery.
I have replaced them now.
Your comment has helped. ;-)

I never have the vents on through air,always have it set to recycle,that way when traveling I never have the constant flow of exhaust gas in the van

Just not thinking

Had a similar thing happen a couple of days ago near Norheimsund. A car reversed up to the side of our van engine running exhaust belching out. Suspecting malicious intent I leapt out to remonstrate. Turned out to be a young lady who was just performing a three point turn when her phone rang, so stopped to answer it. Focussed on the phone she hadn’t noticed where her exhaust was going, when I performed my choking man mime she was mightily embarrassed and apologetic..sometimes there’s a simple reason...just not thinking.
