Unfortunately, this calculator doesn't go up to a 24" rim diameter, but you can get an idea of how changing tire sizes and rims will affect your speedometer.

In 2WD mode, the only extra thing the engine is spinning is a direct drive transfer case- not enough to notice the big difference he is talking about (assuming his 4x4 system is working correctly- IWEs disengaging the front half shafts and the transfer case disengaging the front drive shaft).
There is a significant weight difference with all the 4x4 components vs a 4x2, and again a SCrew vs a SCab, but likely still not enough to describe the performance difference. Then again, hers has a longer bed (all other things being equal, that's more weight).
I wonder, does the OP's truck have the cam phaser issue?
