I'd go with 5w-30 if your temps get down to the teens or less. But then again, your at 130K miles with your current plan, so why change?
FWIW, I used to run 10w-30 in the warmer months & 5w-30 all winter, now I just stick with 5w-30 all the time. Never noticed any type of difference between the two. My rodeo will fall apart (Buffalo NY winters) LONG before any issues related to oil viscosity ranges.
