For myself I try to stay around 65MPH. I do this for a couple reasons, 1st it feels right and safe and 2nd Gas Mileage. At the best every 10 mile increase in your speed is equal to a 10% decrease in MPG. When you are only getting 10MPG a 10% decrease adds up in a hurry. I'm on vacation and its not a race. If you want to pull you TT 80MPH go ahead and in fact please get a head of me. Do you really think you are just as safe as the car next to you doing 80?
Just my Opinion, I have seen to many wrecked rigs in my life to drive that fast with a trailer.
Just because you can does not make it a good idea!!!
Happy Camping!!
