That was what influenced my decision to buy the SRW. Parking, garageability and all that. 5th wheel towing capacity between the two was virtually the same. The two extra wheels on the dually is what makes the difference, I think.
If someone comes up with the correct numbers, I will apologize. I know that I'm getting close to the limits on my SRW. But, since I love the performance and driveability of this truck and, it is paid for.......think it will be around awhile, yet!
Check out the GMC 2016 Fleet Guide
Page 93 spec's the 2016 Siverado 3500HD
Page 99 spec's the 2015 Sierra 300HD / Denali
These pages give the GVWR for both SRW and DRW based on different cab configurations (i.e., Req., Double, Crew) and 2x2 or 4X4 configuration
On average GVWR between a SRW & DRW is ~2,000# (2000# more on the DRW).
It also spec's the maximum payload & maximum towing, but these values will vary depending on engine configuration. Due to the weight of the Duramax it will drop the actual values some.
Hope this helps to answer your question.
