So I just pulled my Dad's 28' 5th wheel over the Pass from Eastern Washington. Not really impressed! Anytime I started to pull a grade EGT shot up fast, 6th really bad, 5th helped, 4th if I wanted to cruise under 50 mph. I easily saw 1300*, quick! The truck has good power if I could ignore egt's! I am planning on a 2000 mile trip in a couple weeks, suggestions on what I might do? Thanks!
