Which axle ratio provides the lower engine rpm at the same driving speed assuming that the transmissions are identical: 3.73 or 4.10?

I have always been under the impression that the larger that the axle ratio was the lower geared the vehicle was. I am looking into purchasing a truck and in reviewing the sales brochure the following data is stated - for an axle ratio of 3.73 the maximum loaded trailer weight is 2,640 lbs whereas an axle ratio of 4.10 is 2,500 lbs (which contradicts my previous assumption). Since I will not be hauling anything on a regular basis I want to have the most economical platform.

I am currently looking at a Ford Ranger Edge - any input here would be appreciated also.
