My recommendation would be to measure twice and cry once. If you measure from the ground to the bed of the new truck and compare that to the same measurement on the old truck it will tell you how much higher the nose on your Cougar will be. Remember 2 or 3 inches at the pin will make a big difference 30' back at the bumper. (I'm sure there's math for that but I don't know the formula)
I personally think the Cougar sits a little close to the ground as it is and I'd like more clearance.
My Ram has FWD and that makes it sit a bit taller, but I've lowered the Anderson ball and raised the Cougar pin box and I'm still nose high. Have not drug the Cougar bumper yet but I'm pretty aware and careful of how I enter and exit driveways and access ways. Would like to have the Cougar raised but the cost is $1250 at a local fabrication shop so the DW has put a halt to that idea.
