OP,
FWIW, on page 601 of the 2014 Ram Owners Manual, under a section called "Towing Requirements" it says:
"• Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
• Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads."
My understanding is that the gears in the rear differential need to burnish to each other. This creates more heat than usual. Thus, no towing for 500 miles, because that creates even more heat. Then when towing, because of more load, the gears touch at a different place on the gear tooth, and have to burnish again. Thus 50 mph limit for the first 500 miles towing.
Just trying to help. ;)
It's your truck, enjoy. Your truck looks great!
