Hi Robert, I sold mobiles and mods for 12 years, but, honestly never heard of that one. There should be a data place on the outside OR a data sheet somewhere inside, try the kit. cabs or the Master BR closet. Also, the owner must have a title to sell it, the make and model would be on that as well. If all else fails, the owner can go to the DMV and purchase a duplicate title.
Hopes this helps.
