Need help with new 173T

I need some help with my recent R-Pod purchase.  I bought the 173T expecting it to have three sleeping areas, as per the website: the expandable tent area (60x74), the sofa (74x40), and the dinette (58x74).  The issues are as follows:

-The sofa has flat pillows to sit on and raised, plush pillows along the back.  When the sofa is laid down for sleeping, the discrepancy between the pillows makes for an uneven, uncomfortable sleeping surface.  Why aren’t the back rest pillow flat like the seat pillows?  Anyone have a work-around?

-The tent area appears much smaller than the stated dimensions, and it appears as though the inflatable air mattress actually is supposed to lay lengthwise in a fashion that would extend it over the couch.  The problem (besides obstructing the sofa sleeping area) is that there is a huge gap between the tent area platform and the sofa cushions (about 8-10”).  If the mattress lays on the platform, across the gap and onto the sofa that gap becomes a problem since there is no support for the mattress.  What’s going on here?

Any help is greatly appreciated.  I like the RV, but it’s my first one ever.
