I have the same truck, with the Mor-Ride and Reese 20k slider. I've used the slider in my driveway as I have to almost jackknife to get the unit in there, bit I was surprised at how tight I could turn before I was going to make contact with the cab.
As far as the auto-leveling (Ground Control 3.0) goes, so far so good. I do have to place blocks under one of the rear jacks (low spot in the driveway) to give the jack enough "throw", but I generally use something under the jacks to distribute the weight a little better anyway.
