question about towing with a new Diesel- any brand

Like others have mentioned here it is best to get the miles on the truck before towing. It gives the truck time to make sure all the seals are set before being put under a hard load. When I got my 2013 Ram 2500 it was very specific to drive the truck 500 miles before hooking up to ANY load.

For me it wasn't a big deal as my family and I already had a planned vacation/road trip shortly after I took delivery of the truck. Instead of taking the wife's Jeep we just took the truck to put on some miles.
