Re: How little engine power is just barely enough?
Yesterday I pulled my 5x8 trailer with dirt bike up the Columbia River gorge. There was heavy deer hunter traffic, it was raining hard, and the wind was blowing 30-40 mph. We're talking walls of water. It was nice being able to put the cruise control on 65 mph (the speed limit) and use all of my attention for steering and seeing.
If I had a v6 or even a smaller v8 I'm guessing I would have had to pay some attention to maintaining speed as well. Sometimes having more than enough power is just convenient and comforting.
