I have a 2014 GMC Sierra 3500HD Crew Cab SRW diesel with GVWR 11,500#
Here a some actual measured weights of our truck that may help.
Empty: 7,980# (payload = 3,520#)
This was with nothing in the bed (i.e., no fifth wheel hitch, no cargo) no passengers, only driver and full tank of fuel.
w/ Cargo: 8,440# (payload = 3,060#)
Bed was loaded with typical stuff I take camping and fifth wheel hitch (PullRite Supper Glide), Large bed tool box, etc., a full fuel tank, only Driver (no passengers),
I would expect my GMC weights would be very similar to the 2015 Silverado 3500 Crew Cab SRW diesel.
You should also take into consideration what the Gross Axle Weight Rating is of the rear axle of both vehicles.
On my 2014 GMC, the RGAWR is 7,050#
Empty: Rear Axle weight was 3,320# (3,730# under RGAWR)
w/ Cargo: Rear Axle weight was 3,760# (3,290# under RGAWR)
In my case the fifth wheel hitch and cargo in the bed load was = 440 - 460#
So you want to take into consideration cargo, fifth wheel hitch, etc. along with the trailer loaded pin weight when looking a weight loading on the truck.
Definitely a DRW will give you much better loading capacity, but as you've indicated, a DRW isn't the best vehicle for unloaded every day driving. That was why I went with a SRW. Our truck is also my every day driving vehicle.
Hope this was of some help.
