Considering adding an aux fuel tank, and then adding the slee rear bumper, ladder, and tire carrier to my HE (and possibly some KO2s). I'm pretty inept when it comes to anything beyond basic maintenance so I'd like to get someone to install these (and point out other things I might be missing in the installation process, such as spacers or a lift). Has anyone had any good experiences with after-market LC specialists in the LA area (or even the greater Southern California area)?
