And for the love of God, please remember trailer towing isn't about speed. It isn't even about maintaining speed. It's about a tow vehicle that can safely do the work you're asking it to do. Many trucks out there are only rated to pull their max tow rating up 6% at 25 mph.
Let the engine find it's happy spot in the power curve, and then watch the temp guage. Ignore the Speedo altogether, except to know when you fall below 45 mph so you can put your flashers on to indicate to passing traffis you are going slow.
Truck engines are made to work, not race.
I am not new to towing. I tow quite a bit. I just usually use my F150 and its only a few hours tow at most. F150 needs engine work at the moment. I was just trying to find out what others thought of my idea.
