Rear end ratios
I've read where some truck campers specify the ratio of gearing in the differential of their trucks used for truck camping. Would anyone out there be so kind so as to explain to me what the advantages...

The higher the gear ratio numerically (3.55, 3.73, 4.10, 4.30, 4.44, 4.56) the more revolutions your driveshaft has to turn to make the tires go 1 Revolution. This increase in gear numerical gear ratio decrease effort required to turn the tires thus making it easier for a vehicle accelerate and pull a load. If you have a light vehicle that does not pull heavy loads you can use a numerically lower gear like 3.08 which decreases the rpm of an engine at speed and thereby increase fuel economy. On the other hand, if you have a heavy vehicle that frequently pulls heavy loads you’d want a higher numeric gear ratio to make it easier to accelerate and pull heavy loads.
