Hello all, new to the forum. I just bought a new to me 2014 1500 Limited Laramie. I pulled my boat for the first time yesterday but could not get the computer to recognize that I was hooked up to the boat trailer. My trailer lights worked with no issues so I think I can eliminate a ground issue? Are there any tricks to get truck to see that my boat trailer is hooked up? Very little info in owners manual. Thanks in advance for any advice. Have a great day.
