WOW, our founding fathers would be sick if they could read this thread, how silly society has become. I realize this is not the place for politics but just thought I would point out the obvious. Government rules are always very unclear, sometimes just going to a different dmv can yield different results for different people.
It is a basic tenet of the rule of law in our society that compliance with one law could not ever put one in violation of another. At least it used to be so. If California law truly states that it is illegal to install an aftermarket converter and VR is complying with that law, then he cannot be held liable for not having a converter on his truck.
Just wondering if you went into DMV and paid the extra weight fees to be able to haul more than the 14,000 lb limit if that would cause an entry into the dmv system that would then make the computer not flag that truck for a smog check.
No smog in Alpine either.
