Will you run it all day? 4 hours? 2 hours? Are you afraid to run the generator at all if you're in the camper? Do you vent the camper after evacuating every time you turn on the generator?
What's the actual difference? See where I'm going here?

Think about it logically.

Now, snarky comments aside, yes CO detector = mandatory equipment IMO, but presume by the nature of your post you're talking running a built in generator to run the air conditioning at night.

1. Intake for RV AC is on the roof of 99% of RVs.
2. Generator exhaust is pointing down and nowhere near the AC. (And if it was a real and present concern, I doubt there would be millions of built in RV generators produced and in use for the last however many decades).
3. Running AC = windows closed (save for maybe 1 or 2 cracked a little to promote ventilation). And the AC is blowing in high volume of air into a closed box, therefor the "box" has positive pressure which would keep errant exhaust fumes from just sneaking in. Unless the wind and climate was "just right" to direct the exhaust from it's far away location up and right to the AC on the roof, without dilution.
4. If it's a LP fired genny, it puts off about half the CO of a gasoline model.
5. Have never owned a built in genny camper until this year and have only left the ole Honda chained to a tree and plugged in to the old campers without issue.
6. Even if a whiff of exhaust gets sucked into the camper, how is that worse than sitting in a traffic jam 4 lanes wide bumper to bumper on a freeway?


The rooftop A/C recirculates interior air only, with no outside air drawn in. Outside air is recirculated on the outside only. Even with a Gen-Turi installed that releases the generator exhaust at roof level, there is no path for the A/C to draw in the fumes to the inside.

Nothing deadlier than CO2. If you must at least use a Gen-turi.


You mean CO: carbon monoxide not CO2: Carbon Dioxide with you exhale and is plant food. And there are many things deadlier than CO, HCN, H2S for just a few.

He isn't running the generator inside is he?
Typo corrected - thanks.

Two separate air systems, the inside cool air (intake and output) is completely isolated from the roof air for the AC itself.

Our CO detector failed a few years ago so I bought a 2 pack of Kidde CO detectors from Home Depot. I didn't mount them anywhere. We placed one at the head of the bed and the other floats around in the living/kitchen area. Maybe you should place one in your bedroom for a piece of mind.

CO is slightly lighter than air so place them about chest high

I have ran my 7500 Onan 24/7 for as many as 6 days many times at the races. Don't seem to hurt them Last DP had over 7000 hours on it and still ran fine.

I have an Onan 7500 and have let it run for 5 - 6 days straight when it was 105F out at the hydroplane races. Just check your oil and antifreeze levels once in a while.

CO is a real concern. Don't believe the nonsense that the exhaust discharges low and the interior intake is high?
RV's in general are not air tight. The underbelly area is not air tight.
Don't be naïve exhaust fumes can and will find there way into the cabin,
If you are running genset overnight use a Genturi and be sure your CO detectors are working.

@Dutch
I was mistaken. But there’s no chance of the AC inhaling exhaust then I suppose.

A fairly big percentage of HH locations do not allow gen use. Call ahead.
