I too have the AT X a 2016 and put on a BAK Revolver X2. Wanted to remove the roll bar too, dealer had no clue. Poked around saw that the harness is loomed into the main and it would be left there. Ended up trimming out the rails to fit around the bar and its still there. Maybe someday Ill remove but then I also need to replace the rails. I also then needed to replace the upper bed plastic as the punched out the front holes for the mounting.
Good to know now that it can be rewired with ease compares to running new ones up there.
