First off - I was having trouble with my left light on my trailer. It would barely light up when both the trailer brakes and the turns signal where on. From reading the many posts on trailer lights, I went straight to the ground, and sure enought that was the problem. I just wanted to say thank you!<br /><br />Next - While I was working under the trailer, I noticed that it may be time to replace the Bunks on the trailer. Why type of wood should I replace them with? The trailer has Keel Rolers, where most of the weight of the boat sit. Would there be any benefit of use 6" wide bunks in place of the 4" wide bunks that are currently there? I am just curious.<br /><br />Thanks
