For a one day trip and if I am going to a typical off-road park or will be doing a technical trail in the Mid-south or Southeast I will typically try to limit my fuel to 1/4-1/2 full in order to save weight. This is because I am never very far from the trailer. At a park like Windrock or if I am somewhere like Moab where I can end up coming out on the other side of the mountain after wheeling all day, I will typically start with a full tank.
If I am doing multiple days (overlanding), I always start with a full tank and know map out my fuel fill options for the trip.
