In order for a TT of the same size as another to be an Ultra Light there has to be reductions in weight. Where are they reducing weight? Is it thinner walls, thinner frame, smaller tires, thinner interior components, etc?
Here's 3 different brands with the same floor plan and all three have different weight ratings and capacities.
