Comparing 2014 and 2015 Palazzo Model

[MisterT]

my mid-year 2014 Palazzo 33.3 bunkhouse has the triple
rails(2top, 1bottom) on the main 'full wall' slide - no problems there
(that's why we purchased it versus the other 2014 that were still
on the lot at MHSRV last August, new 2015's were also there)
but did have a motor in the small bedroom slide fail twice, replaced
both times and no problems since.
300hp Cummins with 2100 Allison Trans has no problems with the
mountains, even pulling our 4bike rack and 2014 FordFiestaSE...

cheers : )

I'm not sure when the DEF tank changed from passenger side to drivers side but that may have happened on late 2014 or 2015.

Dual pane frameless windows

Minor tv brand change

HDMI cables for inside, outside and bedroom tv's

Everything else has been mentioned already

my late 2014 33.3 has everything you mentioned here...
def on driver side(i use for sewer and elec cord storage)
HDMI all three main tvs,etc

:note- not sure why, but main tv and outside tv are 'ContnUS' brands,
which i had never heard of, tho they work fine - but they put Jensen
brand in bedroom(?) only reason I can figure is that it looks like it runs
on 12vDC vs 110vAC(?)
I DO like that the bunk tvs are actual TVs, and not just video monitors!
