Hey guys, I have traded my old trailer and bought a new trailer and I am going to be attaching my trimmer racks, etc, but what advice can you give me about drilling the holes? I remember when I attached everything on my old trailer that I either seem to break the bits, or them seem to dull really fast. What tips do you have for me? I don't want to waste time and I want it to go better than a few years ago, when I drilled holes on the other trailer. What do you recommend I do?
