Run the hell out of it! No tow for 500 miles for the gear sets to mesh.
I agree with Ron, I have a friend that works for Cummins. He told me "work the hell" out of that Cummins. I was concerned about break in time he told me after rebuilds they run the motor to near full capacity. He claims the harder you break it in the better the performance. Just sayin. I'm not too worried about break in.
We took off on the trip we are now on from Milwaukee to Phoenix with 800 miles on the RAM when we left. I now have just over 2500 on the RAM and we're not quite to Phoenix. We're pulling our 38' Mobile Suites which weighs roughly 17k. The route has been all interstate, I 39 to I 55 to I 44 to I 40 until today which we will be on state roads down from Holbrook to Apache Junction.

Service manager at DaveSmith told me to "Run the hell out of it" and I did all the way home from Idaho to NW WA.
When I come to a big hill I just hold it to the floor if needed to maintain speed.
