You can also modify your Honda to run on propane. That way, it will never smell, AND you won't have to carry a can of gas, either. You simply hook up one of your propane tanks on the TM, and you are good to go. And although I do not have a genny, it is my understanding that when you do convert it, you can still operate it on gas. Others here who have done this can comment.

If I was taking a genny camping, this is what I would do.
