I had a gasser dually, CC LB as a matter of fact.
The issues that a CC, LB Dually present are for the most part the same as a CC LB SRW. The width was never a real issue for me.
The length was a problem in my works parking garage and in some precarious parking situations. Just have to do the dually shuffle some times if people park all close around you. (You can park in the back 40.. no guarantee you will be by yourself when you come back to your truck)
As to why a Gasser Dually?
I was pulling a travel trailer with a Golf Cart in the back and my family in the cab... I wanted stability and that's what I got.
Plus I scored the F350 V10 CC Dually for $5,500.00 which I thought was a deal.
Thanks!
