Hi Craig I used rubber lines in the boat. Any time you can use rubber on a boat I always do. It doesn't rust or corrode. I am not sure what I will use for brake lines in the trailer. How hard was it working with the stainless? Are they braided lines? if so that has to be way cool. What actuator did you use? I used the Dexter and am very pleased with it. I have however hit a snag with my fifth wheel come to find out they are not Dexter axles they are Kober axles. I need to find out the spendel size and now that's becoming a pain in the butt. Please let me know how yours turns out. I was expecting the whole change over to cost me about 2k
