My personal diagnostic abilities are not in question to settle any argument to my ability or suggestive rebuttal. And your normal concept of reply's to double dare any responder to try your suggested affirmations seriously drifts off debate.
And in subject to "Not from around here" IS accurate. As I do not reside in PA. But I can assure you my home is not on Planet Mars!
My response's are clear in respect to logical rebuttal. But if insult drift reassures your affirmation to solidify, your image of no one should counter your suggested path to the U.S. by differing of opinion. You leave yourself in that same quagmire our leadership currently expresses by stalemate.
So again for your suggested point to the subscriber of Popular Mechanic. Some 1.5 million (Large)with supposed scientific prowess. How many do you believe will get off their duff and purchase these retrofit kits you claim are straight forward and have the most basic of mechanical knowledge? And have the spare time to take the initiative, after a full work week of politics to undertake this project? While I might add the risk of warranty rejection, the first time into the dealership for service, if installed on a 2001 or newer vintage.
This was your quote, not mine.
"Americans are irrepressible Do-It-Yourselfers"Also on this quote.....
"And warrantee issues may not be as important for truck operators as you might think."I don't just think. I was personally at many Peterbilt & Kenworth dealerships to sample the Service Dept. As we required feedback to the redesign product lines on the road now. And warranty purchases as I know statistics, are very high for a 3-Year / 300,000 Mile Extended Vehicle Warranty On All New Class 8 lines.
And for PACCAR, I can tell you this much. They are in the market to sell new product lines with CNG & LNG. and not to allow competing installers prevail. So it kind of goes without saying. They are not interested in competing with aftermarket kits and warrantying them as well!

Oh, by the way it is very funny you should use Pakistan as an example for CNG usage. Read this article it is a prime example of special interest influencing the government on continued usage or direction to CNG.
