I am aware of three manufacturing plants that operate under the Commodore name. Two of them are located in Indiana (The Commodore Corporation)---219-533-7100 in Goshen, IN and 219-457-3154 in Syracuse, IN. I know this company has been around for awhile and it is likely to be the company whose model you saw in TN.
However, there is also Commodore Homes of VA. I have not heard of any affiliation between these companies. In any case, this second firm can be reached at 804-793-8811.
I hope you find what you need.
