Lonewolf,
We also have a 3/4 ton Duramax, and I agree with the others -- your first limiting factor will be the truck's
payload capacity. Chances are you'll be at/over the GVWR once the truck & trailer are loaded & ready to go.
The Montana's empty pin/hitch weight is listed at 1940 lbs... when loaded, it may be as much as 2400 lbs
(est at 20% of GVWR). 2400 lbs PLUS 250 lb (+/-) for a 5th wheel hitch, PLUS passengers, cargo & fuel, etc.
As already suggested, check the payload # on your driver's side door post... here's the #'s on the trailer.
