Thanks for all of the information here it has helped greatly. But it is time to come to the experts again. I am looking for a trailer to carry my JD 2305 TLB occasionally. I don't ever seem to get the time to schedule a rental so I need my own. I found a dealer locally that sells Big Tex Trailers. I decided on a 60CH and was about ready to buy one. The Sunday before while doing the final research on the web I happened to notice in the specs 2" pine floor. The dealer told me the floor was Pressure Treated. It appears he was mistaken. Is this true ? No where can I find anything to tell me the dealer was telling me the truth. All the specs say 2" Pine. Trailers with treated pine say so.
