Hi, I own a 2007 Ford Explorer. I'm pretty serious about this SUV; I take very good care of it and I do light off roading here and there. I have began going on trails at night and for safety I think I need a light bar as the headlights aren't always sufficient. I looked around and only found bars that needed to be drilled into the roof, and I am a little hesitant to drill through the roof of my truck. Any suggestions?
