Yup. Not going to fix the oil wash...

That's why I suggested the early oil changes.

I don't agree with the long oil change intervals they recommend these days. I know the engines are built to tighter tolerances and oils are better, but that doesn't prevent it from becoming dirty and fuel diluted. Oil changes are cheap insurance for your engine.

Fuel wash/dilution is reason why Ford changed oil spec from 5w20 to 5w30 but I dont think that is enough.

Towing any TT or 5th Wheel at 71 MPH is a risky move. Even though I've done it many a times. (Have been known to hit 80 at times)

But after reading about the tire blow outs from these cheap tires that are put on the trailers today, and going to the tire web sites of the brands of trailer tires used, all of them say maximum speed of 65 MPH.

Maybe with age I'm getting more conservative, (I don't trust the trailer tires made today) but I'm going to slow my speed down to 65 from now on.

The low max speed rating of the trailer tires has got my attention too. I had been routinely running 70-75, and like you, "tested" the EcoBeast on a couple of long 5-6% grades to see what she was made of. Needless to say, I had to back out of it long before topping out ... waaaaay too much speed.

Backing down to 65, she just purrs along in 5th & 6th gear with ~8700 lbs, feeling solid as a rock, and I'll get 10+ MPG at that speed too. I wish they had 75 MPH rated tires. That would be about right.

This thread is rife with the logical fallacy known as a false dilemma.

Our truck looks identical to yours and we love. I did hear from dealer not to use cruise while towing and we keep our speed just under 65. Our tt is around 8,000 dry and we had no issue going through mountains down I81. I'm glad to hear the 8.5-9 mpg is typical because we thought maybe it was our driving.
