I don't regret going to a DRW. The dually isn't my daily driver, so it didn't matter that I bought a DRW.
I did drive it a lot during the first month I had it, just to get some break in miles on it, and I didn't mind that it was so phat and long.... but my commute to work was very short and didn't involve freeways and heavy traffic.
When I drive it empty, I always park in the back 40 of a parking lot where there's plenty of space. Actually I do that with all my vehicles, to prevent door dings and shopping cart mayhem.
