hi tomR...
i'm not exactly sure WHAT your question is...
so here is an answer, it may not be the one u r seeking....
axle ratings were INCREASED for the 2005 models and beyond.
the 'axle rating' for 2005 triples is 3800 lbs...
this was an INCREASE from the 2004 and earlier units...
and resulted in a gawr increase to 11,400 lbs for the '05s.
gvwr was LESS on earlier models and carry capacity was declining b4 this change...
which occurred DURING the 2005 calendar year, but perhaps after 2005 production began...
disc brakes were made standard equipment later in the 2005 product year (march/april),
while the higher segment protectors had been added around dec/jan of the 05 product year.
the ubw on a 'stock 05, along with estimated option weights is HERE..

while the 'limited' model became the 'standard' for classics the last 2 years...
not ALL of the doodads were included (flag boxes, bigger tanks, electric jacks)
my unit was around 9,000 lbs b4 being occupied with the everyday essential camping crap, and has a gvwr of 11,500 lbs.
the current units carry this same limit, i think.
IF you contact a/s and ask for a buyers packet, it will include an up to date 'options/weight' list like the one linked above for 05....
cheers
