Yeah starting to wonder about bearings or something. Deff seems like i have some rolling resistance the more i hash it out on the forum. I did the math and should be around 2350 rpm at 60 not at the nearly 3000 I'm at. So going to look into that this weekend. Thanks for all the help.
I thought the RPMs were kinda high for your setup and speed. That’s why I was asking about the 3.55 gears. But even with 4.10s I would think you should be getting over 10mpg at 65mph. Heck, I get about 10mpg while towing my 30’ travel trailer and EGTs hovering in the 1000* range.
