Are the premium models really better?

[Customer]

Hello, we are shopping and have looked at the Fuzion 345. We are also considering the Grand Design Momentum but my questions refer strictly to the Fuzion.

Keystone calls the Fuzion and Raptor their premium TH models. Maybe someone can explain what that means.

Are the premium models build on separate lines? Separate factories? I doubt there could be substantial differences if they roll off the same lines in the same factories.

They mention screwed rather than stapled construction, is it true?

What about wall and roof construction and insulation?

In summary, I am willing to pay for quality but I want to be sure I am getting quality and not just glitz. I have found the factory website to be very lacking in information regarding construction and quality.

This RV will be used for long term part time and maybe future full time living.

Thanks,
Tim
