What would I do? Sell it all and buy a dually and an AF.
When I was window shopping for a different rig back in 2009, which was before I sold my 2500HD and Desert Fox, I pretty much had my mind set on an AF811.
In 2008 my brother had bought a new truck, a 3500HD Dually Silverado. He said his reason for buying a dually is because you pretty much wouldn't have to worry about being undersized on the truck for hauling a camper.
The logic made sense to me, so I followed suit and bought a dually when I sold everything that summer (of 2009).
For some, A dually isn't a viable option due to he other duties the truck is used for (commuting, etc).
I've daily driven mine, but not on a tightly packed freeway such as highway 176 in Puyallup/Auburn/Kent or I-5 in Tacoma / Seattle.
It was mostly suburban commute, which was fine.
I live in Spokane now, and have daily driven it some - similar type of driving - suburban, not downtown Spokane.
It's a nuisance to park at the sites I visit during the work day, but I accepted that as a fact of owning a dually.
