2WD vs 4WD?
I'm in the market for a 5'er that has a GVWR of 16,600. I've pretty much decided on a 3500 crewcab long bed diesel dually for a tow vehicle. Most of the used trucks I see (GMC/Chev) have 4WD. Is ...

So what's wrong with IFS? You can't say that it's too weak. BTW, I own Rams so it's not like I'm bias, just wondering why you wouldn't own an IFS.
IFS has CV shafts, which add maintenance, and the differential moves closer to the ground as your suspension compresses. I would own a Silverado, just not a 4x4 version. Somebody else defended IFS by mentioning death wobble of solid axle trucks. I have owned 4x4's constantly for almost 35 years, and have never experienced death wobble. Neither have any of my friends that have solid axle 4x4s.
Haha, CV shafts are no more maintenance than the axle shafts and ujoints on a solid axle. As far as the diffs go, they have more clearance than a straight axle to begin with.
The shortcomings of IFS are wildly overblown by the naysayers. They also REFUSE to acknowledge the advantages of IFS.
Having owned both at the same time over 17 years, I can state with certainty that they are different, but both perform well.
We do tend to drive the IFS trucks more as they are just a more refined system. They track better, and have better tire wear. But we also like our SFA trucks.
