Decode for trans & gears
Still confused. Here's my door sticker, 2010 F150 4 door Lariat 4x4 with 5-1/2' box. Wanting to get travel trailer real soon so any advise as to what it's capable of greatly appreciated.

In 2010 all Lariat trimmed trucks came with the 5.4 3v engine which was paired with the 6R80 six speed trans. The "B" in your axle code indicates a limited slip diff, and the "6" indicates gear ratio, which I believe is 3.73
Just googled it, yep B6 is a 3.73 limited slip and just 16 is a 3.73 open diff.

The total weight of your truck, contents, and trailer tongue weight should not exceed 7675#. That is your major limiting factor. So - go weigh your truck all loaded up for a trip and subtract that weight from 7675, that's the max tongue weight of the trailer. Tongue weights are about 12% of the trailer gross weight.
