Hey there man and you're welcome, pretty cool you used to live down this way! I don't have a 4th gen, and although the basics are the same as for mods that will help with performance/fuel economy, you might try checking out the 4.7 mod section for tips on that, here's a link: http://www.ramforumz.com/forumdisplay.php?f=13. As for fog lights, which I'm still looking into doing myself, you can find some info on that here: http://www.ramforumz.com/forumdisplay.php?f=78. Lastly on the antenna, have you considered a stubby antenna? They look great and seem to still get the same reception as the stock long mast antenna. Hope this helps and if you need anything else, feel free to ask!
