In the 80s, the standards changed so you can't have the old newspaper and spit style manufactured homes anymore.
But I'm not sure what exactly you're looking for. Our house is absolutely a "trailer" - it came in two pieces, has long I-beams under the floor, and still has axles down in the crawlspace. I believe one can get the "modular" version which is the same thing, same factory, and doesn't keep the axles (with perhaps a few other changes - it didn't matter to me and was more money for the same end result).
Despite that, it's a solid drywall based house, 2x6 exterior walls, etc.
But if you want more details, you'll have to find someone in your area who sells them and go find out more - my regional knowledge probably isn't applicable to your situation.
