I just got a good deal on a 18' car hauler and part of the reason is it needs a new floor. It will work for a utility trailer with what its got but no way would I haul a car on it right now. At the moment it has 16' 2x8 on it. The question is do I just buy pressure treated #2 lumber from Lowes and use that, or #1 kiln dried from a trailer supply store for a lot more money? Actually 2x10 from Lowes would come out cheaper than using 2x8. I did entertain the thought of using c perlin but I think Ive decided against that. Would be loud and slick and I couldnt find any numbers to indicate which would be stronger c perlin or lumber. So Im open to other suggestions. Budget is of upmost concern.
