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.
Thanks for the nice words. However, nobody has to come to my defense. I have broad shoulders and thick skin and love a spirited discussion or would not be here. But, what is important is that you are getting many opinions on how to solve your issue. And the Houston mostly dually experience, obviously different from the dunes in southern California observations, has opened your eyes to perhaps the hardest places to drive a dually, in heavy traffic on busy city streets. I have driven in the Seattle and San Francisco Bay Area traffic and driving a dually is no different than a SRW in traffic as it is no longer than a SRW truck. Parking in tight places for most of us dually guys is done backing in to a parking place so the elephant ear fenders are not an issue for other drivers as they are negotiating their approach while texting or talking on the phone into the parking space next to yours. It is all doable. What the dually does for towing is impressive and any minor parking inconviences are only that for many that would not tow the trailer you are looking at without a dually. Your best bet would be to compare both trucks while towing but that is sometimes hard to do.
