My truck is up to double digits towing! Just, but 10 and changempg beats the 7.8 I got for the first 5000 mile trip! Still holding off on the chip, everytime I am ready to pull the trigger, the next big thing is almost out! Oh, well. Antifreeze won't come out of the trailer for another 5 full months, so I have plenty of time before the next big roadtrip.
Did a 500 mile trip and going we did between 55 and 62 and averaged 6.8 with a slight wind. was in a hurry to get home most of at 72 and got 8.9 Go figure. The shift point in my trans is so close at 65 and above that it actually felt like the truck ran smother and some of the noise seamed to go away. Don't like going fast but do know when to and when NOT to.
