you may want to air down based on terrain / available traction. I say 4L, and easy on the throttle. You’ve got a 5700 pound truck. Remember, you can only go “too far” once before it makes it to youtube infamy, so be careful.
Agree 100% with
@FordTechOne, use a good strap and make sure you don’t wrap anything sharp or bend against anything that will strain the strap. Free as much of the dirt / roots as you can. If you’re on a farm, F* it and buy some tannerite and detonators, much more fun anyway. If you’re not on a farm... well... at least you get to use your Raptor.
