Getting ready to make a 440-mile run with the 35' Silver Streak in tow. Referring to Post #7 of this thread I'll be traveling at 1600-rpm give-or-take which with the factory gearing is approximately 54-mph.

Some local freeway runs at this rpm show (round trip) the truck settling in at 27-mpg (28.5 uncorrected).

The trip will start at around 2200 Saturday and end near 0600 Sunday morning. Avoiding that killer IH35 traffic north to near Fort Worth.

I've not been able to finish the list of mechanical entails to optimize mpg, but have done a wheel bearing and brake adjust on the trailer. The hitch setting will be roughed-in, and I may decide to get a scale ticket or two. Etc.

Planning to stop twice, with maybe a third.

The combo has hit 15+ in the past.

At the lower speed (and hopefully no winds) 16.2-mpg would be a 40% towing penalty. 30% (the future goal) would be 18.9-mpg.

I'll be excited if I can hit 17-mpg (corrected) for long stretches. The ton mile calculation should be impressive.

Looking forward to correcting the fuel CPM for towing in my sig from the current 17-cpm as prices have dropped as well.

I'll be looking at engine run time to see the actual travel speed. Google estimates 6' 45" for a solo vehicle, or about 65-mph.
