Auxiliary Battery Message

Pretty sure the tow package already comes with the Group 94R vs Group 48 battery and also has a slightly higher amp alternator. I think if you replace the main it would most likely clear up your problems and then after you have ESS working you might want to read the thread on doing the Aux battery bypass and determine if this easy fuse (F42) removal and cable disconnect is appropriate for your needs.

My exact plan. I appreciate all you guys helping me today.
