What did you do to your Class C MH today???

So on our recent vacation I set off the CO alarm twice. Both times were in open parking lots with no obstructions around (~90 degrees with no wind), after running the generator (for air conditioning) right at about the 2 hour mark. This was the first time since having the RV that we've run the generator so long while stationary. The first alarm I thought maybe it was a fluke, but since it happened again a few days later it was now a pattern. :B

No issues running for hours on end while driving.

So yesterday I installed our new Genturi. Also replaced the original (15 year old) CO alarm, and added a second one up front that has a digital readout of the CO level just for redundancy. Also replaced the smoke detector and propane detector since I was on a safety kick.

For the support hanger, I used a Sea Sucker rear tire holder (Sea Sucker makes bicycle racks, I happen to own one already so I 'borrowed' the rear wheel holder). The strap on it was already a perfect length to wrap around the pipe, and with a block of custom cut wood screwed on to cradle the pipe, it's almost factory looking.

Ready for the heat now! :C

There is another way to absolutely keep carbon monoxide out of your RV when running the generator - no matter what the wind outside is doing.

We maintain a pressure inside the coach so no generator fumes can enter anywhere below roof height:

Before starting up the generator, close all doors, wndows, and roof vents except one - which you probably want to do anyway in hot weather when running the generator and A/C to keep the interior cool.

Keep one of the roof vents open that has a reversible fan in it. Switch the fan direction to "air in". Since the fan can't actually bring in any air because all coach openings are closed ... all the fan is doing is slightly raising the air pressure inside the coach.

This slight air pressure inside the coach prevents any generator fumes from entering anywhere below roof height - this includes all cracks, small openings, etc., that might be present in the coach structure. Generator fumes have dissipated by the time they get way up near the center of the roof where the vent fan is located.

This works like a champ for us to keep the inside of the coach fume-free when running the generator. We also use this same method for keeping dust out of the coach interior when traveling on gravel or dirt roads. We only have to use the slowest speed for the roof vent fan to maintain a slight interior pressure.

The only place where this technique might not work is when parking under a roof or in a tunnel ... whenever running the generator. ;)
