Trotwood Travel trailers were built in Trotwood Ohio until the factory burnt down about 35 or 40 years ago. They were considered a quality unit back in the day if you google them you should find a lot of information or at least it used to be there.
ladywendolyn-well I would but just haven't quit figured out how to do it. bigbill-havent found anything on the one I have, other models yes. The way I found out the year was I ran across where a guy in Ohio had one for sale.
