That doesn't sound right..no breakaway? On our maiden voyage back from Rice, we had an opportunity...yes, I'll use that word instead of "brain fart"..to test the breakaway and it worked perfectly. I think I'd be afraid to NOT have it..
As for the propane gas alarm,
Casita doesn't put one in, although it does install a carbon monoxide detector. It would be nice if someone combined the two...both carbon monoxide and propane detectors are said to use infrared
light.
