I use my truck to pull my 10,000 lb 5th wheel RV about 2-3 times per year and a little bit of yard work here and there. But mostly it is my daily driver. Going to work and back is a 16 mile trip on the highway each way. The reason I would like to move to the 350 is so that when I upgrade to a larger 5th wheel RV, I will not be limited by the truck.
