what sorta shape are your tires in? Truthfully, a good set of tires on a bone stock rig can be a ton of fun. Of course, the sky's the limit on future mods but a lot of fun can be had on stock rig with some decent tires. If you're planning to lift it in the near future, hold off on tires till you get your desired height sorted out.

You can go to 3" easily and fairly inexpensively before you need to upgrade any other suspension parts. above that, things get more involved as you need to address driveline angles and drive shaft issues.

Assuming your vehicle is in road worthy shape, get out there and enjoy it! PA's got a couple of good spots to ride. Rausch Creek comes to mind, no idea of the trail difficulty or proximity to you, just throwing it out there. Have fun and snap some pics of your adventure
