Thought I'd start by asking on beyond...I want to tow a light trailer or maybe a Boler with my 09 G37X coupe. Can I just but one of the many DIY install receiver hitches online and be on my way.... Is it really that easy? How on Earth do I even find out how much weight I can tow? I imagine if find that in my cars owners manual? Anything I should be aware of? I've seen tent trailers with brake lights on the back and taillights at night, is this required by law and how does it hook up?
