I finally got rid of my old boat so I was able to begin work on modifying my old trailer to fit my new 1448 jon boat. I got off all the old rotted bunks along with the mounting hardware. Everything went pretty smooth - only 1 broken bolt that gave me problems...I think I'm going to have to drill it out b/c its rusted in there pretty good. Minor problem. Question: Actually 2 questions... 1) If you shouldn't use treated lumber for the floor in your aluminum boat, should you not use treated lumber for trailer bunks as well? (I'll assume the answer is yes). Should I try get cedar or just use regular pine 2x4 & treat it with Thompsons Waterseal? 2) Is it OK to lay 2x4s on edge to use as bunks or should they be laid flat? I've seen trailers rigged both ways. I have beginning pics but I couldn't find my USB cord to upload pics. And, since its 1:50am I'm not planning on looking too hard tonight!
