Thanks ALL... I have never had to deal with timing like this... Truck is due to dealer next week ( the 5th )... I have a company picnic planned on that weekend ( 10th ) with many other trailers..
I have contacted the dealer and told them I will take delivery the following week.. that will give me plenty of break in time before my next scheduled trip ...
The component that REALLY needs breaking in is not the engine or transmission, it's the differential(s). Those crown wheel/pinion combinations are set to very fine tolerances and WILL overheat if pushed too hard too soon. They REALLY need to bed in before taking full load.
Not saying that will guarantee a noisy axle if you don't wait, but it certainly would swing to odds in that direction if you load it up from the get-go!
