curb weight 2007-10 Silverado/sierra 2500 6.0l

[1947hillbillytruck]

anybody know where to find info on curb weight for these trucks?
I need to replace my current 2003 6.6 diesel with a 2007-10 6.0l to be able to haul my RC fifth wheel trailer.the trailer puts down 1377lbs on the hitch ,and that makes the truck to heavy for its weight limit.

here in Europe we have 2 types of registrations for trucks-0 to 7716lbs (B-drivers licence) and 7716 and up (C-drivers licence).,that means a difference in load capasity if truck is B or C.

-so for me to haul a fifth wheel legally I need a truck with low enough curb-weight so that it does not exeed 7716lbs.with fifth wheel.
