Questions about running generator in back of truck

Lots of folks seem very worried about exhaust. So Butch50 let me ask this.

Do you plan to run the generator while parked, having your fifth wheel extended over the generator? That sounds dangerous. Maybe with a bumper pull hitched up six feet away? Yup I've done it several times.

If you plan to run the generator while driving, I myself would not (and do not) worry about exhaust. I figure it gets plenty diluted while driving. I run one or two Yamaha generators in the bed depending on circumstances.
