I hope this is in the right forum. Still new to diesel world and my rig and I want to know answer to two questions that I THOUGHT I knew but dealerships have screwed that up for me by telling me different stories. 
What does a Bighorn Ram offer that the other models dont? Is it a lesser model or a better model? And the second question is: Blu-Tech emblem on tail gate. Does this mean the truck is certified for bio diesel or what? I thought it was just for the new emissions crap on it. Owners manual is not clear on these issues. Thanks in advance for any reply.
