Tow weight

Correct, J2807 is based on full fluids, a 150 pound driver, and 10% tongue weight using a flat deck trailer with heavy weights adjusted to give the desired tongue weight. It's not at all representative of what real users tow or how most of us use our vehicles. I've talked to several people in the industry about a more realistic tow test using an average family of 4 with 2 teenagers and a few hundred in the bed and a max frontal area but because it would result on smaller numbers everyone has said it would never fly as marketing would kill it.
