We tow a few times a year, two of those are 1000 miles each to Canada July and September. Got a couple good hills to pull going up through PA and NW but no real steep ones.With what I learned here and other sites I was sure the 06 was just right for us, so far no regrets.Like I told Mommy though, if I find too many slip-shod recalled build issues happening, its GONE! I've spent a little money on it to get it like I want and I like driving it but as far as loving my truck......... if it ain't breathing I don't love it.
