Is an upper tier trailer worth twice as much (price)?

Livin lite original model was all metal like ATC.

Then they were bought out by Thor. Soon all metal roof gone. Then all metal cabinets gone or optional. I think travel trailers all metal floor gone. They got heavier. I maybe wrong on some of this but the pattern is obvious, all metal roof is a line in the sand for me. I think they dropped torsion suspension on some models.
