Twice I went back to check the date on this thread. I was sure someone was dragging up an old one. :)
Congrats on the new truck. It is silly how many improvements come out to these trucks every year. It is very tempting for me to upgrade from my 2012, but I am still quite a few years away from retirement, and I figure keeping this truck may just help get me there quicker.
But I do agree that life is short and there are no guarantees. If a new toy makes you happy, nothing wrong with pulling the trigger.
Did you ever pull your RV with the 13?
