I currently drive a 2011 Toyota Tundra and I am looking for something that won't work as hard in the Virginia Mountains. I have been looking at the 2018 Ram vs the 2018Tundra. The Ram has a substantially higher tow capacity and payload. Both the Ram and the Tundra have 381 hp and 401 lb.ft of torque, at basically the same rpm's. An automotive engineer has told me that the higher tow capacity and payload of the Ram is only because it has a stronger frame. My thinking then is that I won't feel any difference in towing between the Ram and the Tundra. Am I missing something here?
