Could you snap a pic down the side from straight on?
I am running the same tires on my '13 CTD and considering the AEV Katlas. Wondering how much they will stick out.
I don't currently have any flares so that might be required.
New to the forum. I'm following your thread as I have a 2013 2500.
As far as sliders go, have you seen White Knuckle? http://white-knuckleoffroad.com/powerwagon.htm
