Just looking for honest info

Comparing DRV Fullhouse, Vanleigh Ambition and Luxe. Noticed that the Luxe price point is substantially higher than the other two. In fact, approaching the cost of a custom New Horizon or Spacecraft. So I called Luxe and spoke to a very pleasant salesperson and flat out asked what makes your RV so special that it's priced comparable to a New Horizon? The salesperson said IT IS as well built as the New Horizon. I asked for, and received, pictures of a toyhauler build in progress. Guess what? The frame is manufactured by Lippert, as most are. There are very few manufacturers that design and build their own frames in house. The New Horizon frame is what makes the dang thing so heavy; 30K lbs for the 45' model.

So I ask,has anyone completed a deep dive into the differences among these three toyhaulers?
