I agree with NC about the wife driving a dually. My wife loves ours, whether as a daily driver or when pulling the fiver. When we are on a road trip, she is always asking if she can drive. The only thing is - she wants me to park the fiver, especially with a back-in. She likes to be outside to give me "advice" on what to do. :D
Parking: I used to park way out in the lots where there was a lot of room. But now I have no problem with the width and can usually put it in the space with the "hips" within (close, but still within) the lines. The only drive-thrus I don't attempt are the ones with a narrow drive and a tight turn. I take that back, we have one Starbucks drive-thru like that and I can get it around the turn if I go up on the curb a little on the curve. So, for that one, I normally park and go inside. I agree that the length of my truck (23') is more of a problem than the hip width. A minor problem with the drive-thru is that you can't get as close to the window and have to reach a bit farther for your food. But that is really a nit.
The one thing I can't do is use the automated car washes. The dual rears won't fit on the tracks and the scrubbers would not be good on the hips.
But all-in-all no real problem with my DRW.
