Its already been said but ill add a bit to it get a 1 inch lift shackle (2 inches total longer shackle). Then if your dad will let you add a leaf to your spring pack. It wont sag as much when loaded and can be done basically free except maybe a longer center bolt in each leaf pack. So for shackles and bolts your looking at like 50-60 bucks and a good saturdays worth of work. You shouldnt need longer shocks. And it will sit slightly higher at rest and will feel firmer on the road and less body roll in turns. Although it may not be as soft of a ride but your young enough to not care.
Plus it would be a good time to get some time underneath your vehicle to look and learn and inspect what goes on under there. Everytime i buy a vehicle i always jack it up in the first week or so and crawl underneath there for 20 minutes or so to familiarize myself with it.
