Probably one of the more important things in all of this, and one of the reasons I have a somewhat cavalier attitude about the topic, is my state does not have any enforcement on a private party level. To be honest, I didn't know any states do but some of the chatter I've heard makes me think some do. I'm much more just looking at the physics - A 2500 is the same truck as a 3500 except for some rear suspension beef. Add the beef and you're good to go from a physical standpoint (this is why I get annoyed at people saying I'm risking my safety and everyone on the road).
My point is research your local laws and rules, read threads like this, and make the best decision for you.
