So, if I’m pondering a diesel 3500 SRW 4wd in the future, what does it give me over the 2500? After scoping specs, (all 3, but leaning Dodge), I don’t see spits dif in towing, just bigger payload in the 3500, which isn’t a huge thing for my use or need that I can envision. It’s got me leaning 2500, unless I want a dually.....which I don’t. Just thought I wanted a 3500 for covering my bases, but seems without two wheels, they’re just 2500s with stiffer rear suspension/higher bed capacity?
