Well I did it. Salt Lake City to the middle of nowhere Wyoming and back. It was 720 miles roundtrip up and down Parley's Canyon (6% grade). I have an 05 f-150 SuperCrew 5.4 with tow package. I was a little nervous going that far but my truck did a great job. going up parley's was a little rough at the top I was going about 35 mph at 4000 rpm but I made it. I was towing a 27' TT weighing approx. 6500 lbs.

Just want to thank everyone on the forums. I gained a lot of knowledge from reading about everyone else's experience.
