I live in Iowa and I use 10w30 in a 2015 2500 6.0L. It is extremely rare to see temps getting below -20F, and the pickup resides in a heated garage when not being used. Same for my 2006 Cadillac CTS 3.6L, 10w30. Same for my commercial semi truck, 10w30, but in a HDEO variety. It doesn't sit in a heated garage when not working, but it does have an oil pan heater. In fact, everything from my Yamaha portable generator on up thru the semi all get a 10w30 of one form or another and various brands.
