Car hauler trailers

Okla has always been the place to go for any trailer. Guess maybe still is??? I have had a few 18 ft with dovetail, steel or wood floors. The one I have now was bought new out of Chicasha. Never titled, never tagged, never a ticket and its been everywhere! Has sat outside what? 25 years, the tubbing cross members might be getting a little thin? I have replaced that wood floor a few times or so! I prefer the steel treadplate but some say its slick. LOL
I would prefer trailer made in Ok over one mad in Tx. I bet OK will be better and cheaper.
