I'm not making anything up. I own a landscaping company. we also do snow removal as well. we own all 3. mainly gm. but own a few f550s. and a few cummins. Nothing newer the 2014 for the cummins or fords. all 3 are great. pull great. the Fords have higher gvw then gm. which is why we own them. can haul more legally. anyway, every straight axle I own, I cannot make the same years I get out of the ifs trucks. Tire wear is horrible, drag links, knuckles ect.
For pulling, most are trucks are dually, but I know, in my opinion, the Dodge seem to have the softest feeling rear ends of them all.
I do like the interiors of the ram tho. even tho most ours are not loaded, they are still nicer then the equivalent gm. Now my personal denali I own, is pretty nice, I like it, can't really say I'd pick a ram interior order it.
