Well im going to be upgrading one of my trucks in march and still trying to decide exactly what to look for. I really want to go to a DRW but i have my concerns. Obviously theres 2 extra tires to replace, which are now even more expensive. I have heard that they get worse gas mileage than the SRW brethren. And i plow in the winter. So the extra width i am concerned about. Hitting things and less down pressure on the rear tires. March through November though, i am pulling a 7,000lb enclosed trailer. I dont pull anything over 7klbs much, but i do about once a month. Which is a bobcat and sometimes a loaded dump trailer. So it would be nice to have the dually for extra load capacity and easier towing. What do you guys think? And those of you that have went from a SRW to a DRW, did you like your choice? SRW=single rear wheel, DRW=dual real wheel.
