What gears do I need?
Looking at a Ram 2500 to pull a 7K travel trailer. It will be a gasser with the 6.4 hemi. Should I get the 4.10 rear end or will the 3.73 do what I need?

The 4.10 gearing will not give you more horsepower.
Gearing will not change the horsepower of a vehicle period.
Only modifications to the engine can increase horsepower.
Not sure why this keeps getting repeated.
We know gear ratios don't change what the engine puts out.
They multiply (or reduce in the case of overdrive gears) when get's sent to the tires to drive the truck forward.
If they didn't matter, all vehicles would have 1 speed transmissions and 1:1 rear end ratios.
