difference between srw and drw

[thor]

just my opinion on these subject.i had a 2500 2003 chevy diesel.just bought the 2011 chey dually ltz diesel.more power and all that stuff.the biggest difference that i really notice is hoocking the fifth wheel to the trailer as far as reaching the handle of the wheel hitch .i am 6 foot tall and reaching over the dualle wheels is next to impossible.so now i have to crawl in the box to reach the handle since the box is 8 foot.any comments or answers on these subject? other then that i love the truck.
