I had a '65 F-350 with NP 435 transmission and a rear axle, I think, from a duece and a half, definitely larger than the typical 1 ton axle. Rear axle ratio 5.125:1. NP 435 granny gear was about 7:1. It moved about 2 mph at idle in first or reverse. Sure faster than a baby's crawl but I pushed out of getting stuck a couple times and had no troubles catching it when it was moving on its own. I didn't have to run to catch it.
So its overall engine to axle ratio was about 35:1.
A good 4 or 5 speed old time truck transmission would have that 6 or 7:1 lowest low and probably at least a 3.8 or 4.10 rear axle. Stacking two of those transmission would make it move slowly, but if you goosed it, the drive shaft would probably twist if the tires didn't slip. Overall ratio about 140:1.
