    Hi!
    I know, the 4.7 is limit to tow a RV trailer, but I was wondering if the P2447 on the truck could be the cause of the 9.4mpg (25l/100km) consumption of my truck.

    I tow a 28 ft 7700lbs rv trailer with torsion bars. And I respect all weight limits on the truck.

    If the code is not the issue, is there a way to lower it's consumption a bit? Thanks.

    Are you saying you get 9.4mpg while towing? Thats normal. Bad news is your code is for SAIS. Not cheap or easy.
