Least comfortable vehicle I've ever had the displeasure to have been
unable to avoid driving.

Sleeper curtain can't keep the light out, curtain nearly six feet tall,
has only four tabs of velcro two inches long by one inch wide.
Sleeper LED clock bright enough to read by, and has no facility to turn it
off.
Designed so that people of short stature have to stand up to fully depress
either the accelerator or brake, wife had to use a hyperextended posture
with her bottom off the seat in order to brake hard or to mash the
accelerator (does this sound safe, an 18-wheeler with a driver who can't
sit in the seat, but has to stand?).
Window in the sleeper (a bad idea in general) had a curtain that allowed
light to come in straight down on the driver's face.

Many good features in the vehicle, I like the idea of drawers rather than
cabinet doors. Freightliner uses cabinets with doors that rattle, this
sleeper posed no noise problems, but if you can't shut the light out, the
sleeper adds no real utility.
Many good points, lots of nice touches and bells and whistles.  These mean
nothing if you can't actually drive the damn thing, or if you can only get
an hour's sleep while spending five in the sleeper.

Volvo may make good cars, but their trucks suck.
They suck bad.
Their engineers should be made to live in their abominable creations for a
couple hundred thousand miles.
