Yes - whenever necessary while drycamping in hot, humid conditions. That's one of the advantages we get from laying out all the money for self-contained RV's with convenient built-in generators - so we can be off the grid and still be comfortable in all conditions.
However ... whenever we do this we make sure to maintain a small amount of air pressure inside the RV to automatically prevent any generator fumes from entering the coach. We do this by closing every window and vent in the motorhome and cab except for the one roof vent with a reversible, multi-speed fan in it.
We set this fan to blow IN on it's LOW setting. The fan can only "try to" bring in air from above the roof because all other coach openings are closed - so very little actual "air flow" within the coach can take place - except for air being forced from inside the coach to the outside of the coach through any small cracks, etc.. What the fan does is maintain air pressure inside the coach so that the generator fumes from down low outside the coach can't enter the coach through any openings down there.
We use this technique all the time ... it works great to keep generator fumes out during the night or during the day. It also works the same way to keep dust out of the motorhome when traveling on gravel or dirt roads. ;)
