Who has driven or rode in all 3 Brands? Currently have a 2016 Ram 2500 and hoping for a bit better ride when I hopefully upgrade if things settle down. Starting to get used to the new GM's so not opposed to that, does the IFS help out? I hate test driving vehicles and dealing with salesmen so I would not mind narrowing it down. Also what are you guys with newer diesels getting for mileage city/highway mixed?
