Good idea.
The 1500 Ram has a very small 3900 rawr which is the lessor of the axle rating tires/wheels or rear spring pack.
The 5.7 hemi with a 3.92 axle ratio won't have any problems pulling its tow rating....but those small rawr limits how much load the truck can carry in the bed and on the rear bumper.
I've seen some folks with their bars cranked up so high the rear tires on the car/truck wound loose traction as they were pulling into a gas station. So how much load can the system take off the rear axles has too many variables.
