A grounding issue does make sense. Perhaps I was a bit rash in immediately sending everything back before coming to the forum.. lesson learned. Regardless, I will be doing much more research into the CANBUS issues and ways around them for our trucks. Thanks for the help.
Make sure that you are ordering vehicle specific hardware and not universal kits.

Consult with DD in advance to make sure that the products you're selecting will work without issue in your vehicle.

From the grapevine, their CANBUS adapters are known to work very well, so I am finding it interesting that you're having problems.

Either way, they will get you squared away!
