I was reading an article where a lot of big truck owners were very upset with new legislation in California because all big diesel trucks have to have smog devices installed by 2014 which cost lots of money to install.
Now my question is, do diesel pusher coaches fall into that category?
I don't know the answer but do know that this subject has come up before on this forum..If you google "diesel smog devices in CA" you will see the response I just mentioned, plus other info.. Good luck.
It's my understanding also that motorhomes are exempt, at least for now. I work in a large fleet shop and we have had to install some very expensive exhaust particulate traps on all of the older trucks. Some we decided to just auction off and replace with new rigs as the modification was cost prohibitive to the age of the truck. Some were able to get an exemption on if they are driven less than 1K mi/yr (local construction units).
We also had to replace several of the pony engines and diesel compressor trailers with units that meet the standards. A real PITA and a whole lot of money.
The exhaust modifications FWIW run between 15 to 25K per unit. Lets hope they leave the RV industry alone regarding these mods. A whole lot of folks out there will be impacted.
