Don't Motorhomes manufactured after 2005 have to be smogged anyway? Are we just talking about older models (like mine) that were previously declared exempt? If you had to live through 6 months of very unhealthy air, due to the fires in CA 2020, you would likely be in favor of any measures to improve air quality. I will continue to live in So Cal try to squeeze a few more grand trips in since the motorhome is paid off and still runs.
