Lightweight is nothing more than a marketing buzzword. In most cases so is 4 season, arctic package, aerodynamic cap, fuel saving underlining, 1/2 ton towable, etc etc etc. My Rockwood Roo Hybrid is advertised as "lightweight" despite it weighing substantially more than trailers of the same size that are not marketed as "lightweight".
Folks need to read and understand this. I mentioned this long ago and was "corrected" by fellow members.
To prevent flex in my ultra-lite frame :W I added a third pair of scissors jacks just in front of the axles. Think of the frame as a bridge standing on the far corners, it doesn't take much to bounce the middle. Flexible tires and springs won't prevent the bounce.
