Hi,
I'm happy with the power on my 5.7 have towed my new 5th wheel on three mountain trips in Az and Colorado. Trailer is 6400 lbs empty and about 8000 with water and gear. Have averaged 10+ mpg going 65 when I can.
My only complaint so far is the grabby brakes and odd shifting in the tranny.
Looking forward to exploring this forum!
Mike
