In jmtandem's defense, I did start this post because the Chevy DRW truck was causing friction here at the house. But as shooterdad has indicated, the thread has evolved and given me options other than the ones I thought I had.
Here in the Texas Gulf Coast area it seems like there are hundreds of 1 ton DRW trucks being used as daily drivers. But the closer I get to the crazy traffic of downtown Houston, the numbers of duellys decrease dramatically.
I had not really considered the 1 ton SRW vehicles because none were available at the local Chevy or GMC house. The Chevy salesman repeated the same old line that the 1 ton SRW is just a slightly upgraded 3/4 ton truck and not worth my consideration and once again I blindly believed him.
Also on this thread a link to specs for the Chevy trucks was posted that had all the info I tried to get at the dealership. With that I've been doing the math. Calculated with a full tank of diesel, a few extra passengers (not expected) and a few extra pounds for the unexpected the numbers indicate the SRW will work.
My next step is to find a truck on the lot so my better half can give it a try. Since Chevrolet is already phasing over to the 2015 model, selection may not be all that great but I bet I can find something out there.
Again, thanks to all for the help. It is all really appreciated.
