2016 Palazzo 33.2 sofa bed air mattress needed

[Blondie]

We own a 2016 Palazzo 33.2...love the layout!
We're hoping that another 33.2 owner would you please be so kind as to tell us the dimensions/size of their (68" seating length) sofa's air mattress plus the brand name(s) and model #(s) for the sofa air mattress and remote that Thor supplied with their 33.2 Palazzo unit.

We need to use the sofa bed this June. Unfortunately, we've already received and sent back two wrong-sized air mattresses from our dealer.
Knowing the correct brand and model #'s might be a big help.

Thanks for any help,
Bette & Dave Slag
