Can anyone suggest how to run the 12 ga wire to the battery for the lights? I've read that you can go under the car or run it through the interior. Going through the interior sounds like a big pain in the ass, but it also sounds like the wire would be better protected from corrosion.
I have a 4x8 trailer that I used to pull with my 2002 Honda Civic (I had it professionally installed but this time I want to save money). I hauled all kinds of things with it and it never started to sway on me. Not once. I've hauled cinder blocks, logs, riding lawn mowers, motorcycles, big screen TV's, etc. on the interstate. I'll get a hell of alot better gas than any pickup truck out there too. Don't drive like an idiot and you won't find yourself getting into stupid situations.
