Stuff done during the summer - How much force is needed to move an S10?

I need to find out some clearances and verify a couple of measurements. Maybe it's time to remove the back of the truck.

Remove the cargo box from the truck
remove the skid plate below the gas tank
remove the gas tank
install a target for the tachometer on the drive shaft
verify the gear ratio on the rear end. Jam the passenger side wheel. Turn the drive shaft one turn with a pipe wrench. Count the revolutions on the driver's side rear tire.

3.5 revolutions of the drive shaft to 2 turns of the rear tire. If the passenger's side tire was not jammed, each tire would have turned once. The internet lists 3.43 to 1 as a typical gear ratio for the rear end. That's likely what I have. The other option appears to be 3.73 to 1.

I tried a few different ways to jam the accelerator and measure the rpm on the drive shaft with the tach. No success.
