It's pretty high stock. I had to buy a tire step on Amazon to work the hitch because I'm not as agile as I used to be and climbing on the tire was getting very difficult. I'm 5'11" and I can walk up to the truck and rest my arms at the armpit straight out. It measures 56 3/4" at the front of the bed and 58" at the rear of the bed with no load, except the hitch. Haven't measured it, but just eyeball, it sags maybe 2" when hitched. My only change is adding Timbrens, which doesn't effect the truck at all until under heavy load.
I do have about 8" clearance between the bed rail and the 5er when hitched and it rides just a touch nose high.
Oh, also I have the 20" tires if that matters. 2014 offered 18" and 20" depending on the package. It's funny, the tailgate came with a pull out step and hand hold post that pops up. The step is so high, it's almost useless without stepping on something to get up to the step.
