F450 vs Ram 3500 DRW tow vehicle

^^^^ The thing is pulling an 18000 lb rv down the highway at 70 mph is light work. At 2000 rpm the 2020 Powerstroke can make approximately 380 HP. Even if you have an RV that requires 180 HP to tow it down the highway at 70 mph, why would you want your truck geared such that the engine revs to an rpm where it is able to produce over double the required HP? 4.30 gears are too deep for us RVers, especially when they are offering us a 10 speed transmission. If you have a 10 speed transmission and 3.55 gears and find yourself towing against a wind or in light hills and find the transmission is dropping out of 10th too often for your liking, you can simply lock out 10th gear.
