Hi. I'm planning to replace my bunk-boards on my boat trailer the next time I take my boat out, as they are looking pretty weathered & the carpet is a little torn-up too. I was wondering if I need any "special" type of 2x6's (that's what they appear to be anyway) for this replacement? If they are "special", where could I purchase these at? I'm in Southern Cal. (high desert). Also, what kind of alterations will I be looking at too fit these things on? (ie:drilling, sawing, hardware, etc.) Sorry for all the questions, but I just want to be prepared when I replace them, as I'll be doing it in the parking lot of where I launch my boat at (Silverwood Lake). My boat is a 18ft. Challenger jetboat & I'm not sure of the brand of trailer it is, but it is a double axle trailer, if that matters. Thanks for any advice you can give me. I appreciate it very much. Thanks again...JT2Fast4u
