This has been my thinking for a while now. I hear a lot of people on here talking about how much better the newer 1/2 ton trucks are compared to the old ones, how they are nearing the older 3/4 ton trucks of a few years ago. Everyone will agree that many of the older trucks were rated very conservatively, and I have a feeling that manufacturers are now just rating their trucks higher.
I have done my share of work on 1/2 ton as well as 3/4 ton trucks and there is just a huge difference in how much heavier the stuff is built. Admittedly, I don't do a lot of work on newer trucks, so I kind of keep this to myself usually because I can't confirm it. I don't think they are putting dana 60/70/80 full float rear-ends into the 1/2 tons yet, not the much beefier yokes and u-joints that I see in older 3/4 tons. The tranny's might be a little better (not sure), but I don't think the transfer cases are any different. They also still use 5 lug wheels (some 6). Also, do they have the larger radiators, steering boxes (actually I know that many have gone to rack and pinion), power steering oil coolers, larger alternators that came from the factory on many 3/4 tons? Again, I don't know because I don't have a new truck, but find a lot of the hype about how much better the newer 1/2 tons are a little exaggerated. It would be hard to convince me that they are "about as good or better than the old 3/4 ton trucks". More powerful with better trans... yes, but I doubt that they are just as heavy duty- just rated higher.
I am sure I will get flamed for this, and maybe I am way off... so go ahead and educate me, maybe I need it.
