This is what I like the most about this forum. There are always multiple ways to skin the cat. Ironically it was the OP's critiques that lead us to go lpg instead of diesel. kevinmcc08 I am sure that your choices will be best for you. I am not sure if the exhaust on a generator is as dirty as a truck nor do I suspect there are emissions reduction requirements. Assuming the exhust is routed properly I wouldn't expect any issues with regard to exhaust. I do know that the Onan we selected was also offered in a diesel variety of the same dimensions that is designed to fit within the standard install location.
