We've had both SRW and DRW with large 5th wheels and prefer the dually. Just gives more control and security. And as far as DEF is concerned, we bought one of the last dually 2007 GMC Sierra "Classics" around. GM changed models and engines mid year when the new exhaust control rules requiring ultra low sulpher diesel went into effect 7/1/07. We were in the process of retiring at that time and had found our favorite snowbird destination in San Carlos, Mexico. We've spent every winter there since 2007. Mexico doesn't have ultra low sulpher diesel except at a few stations along the border. My Duramax runs just fine on Mexican diesel. Anyone with a newer diesel engine, with DEF and requiring ultra low sulpher diesel is supposedly risking engine damage running the regular Mexican diesel.
