Let's go with the facts.

1. We know it is 12vDC by your verifying previously. The back of unit will also confirm,
2. You have found the 12vDC Distribution Panel, actually covers both batteries
3. The Gas Detector is not on the panel so it does not have it's own fuse on the panel.

So what would I do?

1. I would first confirm that all DC fuses are working (not blown)
2. Assuming all DC fuses are good then you 100% no doubt about it have to have a inline fuse for the Gas detector or do you have 12VDC Circuit Breakers
3. Go to House batteries and look for separate leads coming off the positive posts, that inline should be within 18 inches of batteries or so if it was done professionally.

If it is inline is not seen near battery you will need to go back into coach to trace the wire to see it's power source. Also don't discount a 12v transformer somewhere that is off 110AC. Not too hard to check the AC breakers just for sanity sake and to add one more known fact to the equation.

My coach a Winnebago has 12vDC fuses and two 12VDC circuit breaker panels. It is nice to just need to push reset button and keep going.
