Ford was able to publish J2806 for the 450 back when the article was printed Ryan is referring to. They were NOT able to come close to RAM's numbers with their 350 so they did not participate in the SAE rating until their completely new 350's came on line. I am fairly certain all three go by SAE now.
FYI RAM does not strip down their trucks to get the carrying capacities that some are or were doing.
