Several years ago the forum had a thread ruminating the idea of a 6.2 Ford diesel conversion for the armada. Now that Nissan introduced the 5.0l Cummins in the Titan XD has there been any progress towards converting an Armada with the XD setup? Seems more feasible now than before. My Armada tows my travel trailer ok, but there are instances where I could use a bit more oomph. Also figure fuel economy might be improved with a diesel. Not worried so much about fuel cost but travel range. Also with the cost of used trucks in this economy a swap becomes intriguing... thoughts?
