Great way to break in new truck. I picked up in Augusta GA and drove home to CO/NM Four Corners in 3 days, ~1800miles. V6 engine is rough initially: take first 1000 miles easy, low revs, just cruising at 80 at 2000? rpm. Then it really starts smoothing out. Oil change asap when you get home.
Route - there's no interesting geographical way across the flat lands; you're either sucking it on I70 from Denver via KC to Nashville before the beautiful Smokey Mountains appear, or you're sucking it on I40 across the Texas pan handle. I've done both routes, and prefer the southern I40 because you get a bit more of the Rockies on the NM/CO end of it, and the roads and speed limits in Texas are far superior.... although the food and restaurant options are better on the northern route; great food options in Nashville and KC.... not so much in Amarillo or OC.
Either way, load up on podcasts and enjoy the journey and the time, and by the time you're home, new truck will be all broken in and ready to play.
