Right now I am towing it with a Yukon XL. It does sway a bit at times, but I'm not sure if that is the light weight of the Yukon or the SRW aspect. Probably a bit of both. I'm thinking that with the length of the trailer plus weight in the bed that might be sitting up higher, a dually might be the way to go.

 

I bought a 2009 3500 dually mega cab and I thought it was way more truck than I needed UNTIL I hooked up to a recently purchased 38ft 5th weighing in at 13000lbs empty. After the first 100 miles with the new 5th wheel I thought WOW im glad I got the dually! I personally dont mind driving in and out of Atlanta everyday for work so I guess you get used to it!

 

The only way I would consider a dually is if it was a 4X4 mainly because I spend to much time off the pavement. On the road the Dually is the only way to to go, off the road...
