All ActivityMost RecentMost LikesSolutionsTowing Question for a new 2015HD GMC Denali PUI currently tow a Saturn behind a 40' Country Coach and recently purchased a new pickup that I would like to be able to tow. Unlike the 2014, GMC states that the batteries need to be disconnected in order to flat tow once the transfer case is in neutral and tranny is in park. By doing this, I will lose all presets so wanted to see if anybody had a solution around disconnecting the batteries but being able to disable the steering lock and use existing 12v for my Brakebuddy? Lastly, has anyone found a pre-made wiring harness the 2015 GMC Denali Pickup?Nice RV parks (big rig) within an hour of Seattle?I am having a difficult time finding big rig parks with good reviews near Seattle. Any recommendations for a 40' Country Coach w/tow would be appreciated.
