I recently test drove the 2016 f250 xlt fx4 6.7 before i bought the titan xd. Thought the F250 was bigger. Tonight I stopped off at Walmart and when I came out had a few people parked around the xd. They were questioning if it really had a cummins. They really had no clue about the xd just saw the cummins badge. One of the trucks was a 2012 f250 4x4 the other a ram 2500. Without getting a measuring tape parked side by side the xd looked bigger then the two. Just shows you how big it really is.
