I would advise A team to employ the expertise of dieseldoctor prior to his truck purchase. Seldom can any changes be made once a truck is scheduled for production. If you are building a new house you can implement change orders for additional monies, however manufacturers will not change a production line for a customer.
With having vendors from all the manufacturers, consultants, and "high level engineers" as A team has claimed for his truck build, I am surprised this basic topic was not discussed.
A team says they came in from all over for his one truck build for free. I would hate to think one paid them something and they left out the above.
I would follow your own advise and hire dieseldoctor. (Great innovative work)
Have to get that vendor meeting started sometime!
