Afternoon, I do not own a Cascade, however I do own a 2020 Mammoth and have been through their plant in Bend. Follows is what I think are two important factors: each opening window-hatch etc is framed, the through bolts and backing plates.
I have previously owned an Airstream trailer and an Artic Fox tc, Host is ahead of their respective products. We have over 45 nights in our Mammoth.
I will echo a prior comment-contact Randall P at Host: he will be quite helpful and ends up speaking with the vast majority of Host owners. The factory support after a purchased has been first rate!
