Same here, Ken. I just keep hooking it up to the 5th wheel and going. No problems to date (took delivery on 9/11/10) - just routine service. I'm getting around 10. 5 mpg towing our 16K 5th wheel which is about what I was getting with my 2002, so I'm not even going to complain about fuel mileage.
Merry Christmas to you and yours as well.
Rusty
