Along with what others have said: On a 2014 rig, I'd suspect your tranni and engine have live computers in them wired to bypass the Salesman's switches. This keeps the Adaptive Memory remembering your engine's On-the-fly settings and shift patterns. Then there is the memory in the dash radio, and the CO and Propane safety devices.
Cure is to disconnect the ground cables from the House & Chassis batteries. Takes all of 5 minutes. I keep a tool in the battery compartment just for that job. The adaptive settings for your engine and tranni will restore themselves after about 100 miles of driving. The radio you'll have to restore the stations yourself.
