Follow the Owners Manual
FYI, when put into Toad mode and turning off the ignition, normally the EPS will shut down. Most FCA cars/trucks do this (older ones) Some of the newer ones will keep power to the EPS so that the front wheels will self correct. There should not be any issue with a Ram 1500 only because of the weight of the front end. The lighter cars can get the "Death Wobble" for several reasons, front end is too light with the EPS off; The Tow bar setup is not correct, it lifts the front of the Toad up slightly releasing the pressure on the front; slo in the tow bar setup, if you can move the towbar side to side and or up and down in the receiver and hear or fell it clunk then it needs fixing, this causes the Toad to magnify the sway and cause the Toad to oscillate (Death Wobble); Aslo this takes a toll on the connections to the Toad especially if you don't have a proper tripod setup to the Toad. Most Base Plates don't tie the front of the Toad together so they oscillate and wear out the front chassis connections, you need an extra brace between the chassis points where the plastic bumper sets to make it sturdy enough to handle the towing. This is why allot of owners of Jeep Wranglers and the like don't have an issue because they have replaced their bumper with something heavy duty to install a winch.
