I’ve owned all 3 majors over the years and consider them all to build good trucks. I’m not brand loyal, but have tended towards more GMs. I had my GMC 2002 3/4T for 11yrs and ~180k miles when I replaced it with a 2013 Chevy 3500; that now has 175k on the odometer and I’ve ordered an F350 that I’m looking forward to getting in a month or so.
Interestingly, last week I took a look around the campground we were at. Ignoring grocery-getters, the distribution of 3/4 & 1Ts were as expected: 7 Fords, 8 GMs, and 6 Rams. All good trucks, and about the same distribution I seem to see running down the road.
