My engine grunts louder too at that speed. It lasts from about 3000-3500 RPM then it quiets down again. I figured it had soemthing to do with intake. exhaust, or harmonic balance, but if it's a 4WD thing, then I have no idea. I wouldn't think the extra weight would cause that but perhaps different routing of the exhaust (is it different???) could cause frequency changes. Beats me!
i have never noticed any weird sounds or noises- just that the engine has to work harder to do the same thing (sorry for the confusion there)- its not as 'peppy' in most driving situations, then again, you dont have 4wd either. there is enough difference to justify different shocks (and torsion bars?) and its enough weight for the ride height of the 4wd to be slightly lower than the 2wd.
i guess it would be the same as if you had a couple buds in the truck, but i've never noticed the truck labor with 2 people in it.
