You’ll be within the limit even with two people. You should be okay in that respect. Personally, would opt for the V6, but that’s just me. Though it should be mentioned that the I4 gets about 3 MPG better than the V6 in a 2WD truck and 1 MPG better in 4WD models, so if you’re getting a 4WD model there’s isn’t as much as a MPG penalty.
