Here's my new (to me) truck. 2009 extended cab LT 4.8L 2wd. I put on some u2-55s.
I built a hybrid half fiberglass/half mdf single 8" sub box with approx .875 ft^3 volume, that is sub box halfway across, and under seat storage on the passenger side.
Ill throw some rear shackles on it when the weather gets nicer to level it.
