I was in Vegas for the day and I saw a white Ford f550 with single rear wheels. This truck had oversize tires, probably 38's with maybe a 6-8 inch lift. I thought I was seeing things so I tried pulling up to the side and I definitely saw the 550 badge on the side as well. Pretty sure I saw powerstroke under that. We were traveling on the freeway in pretty tight traffic so when I got close to him on the side he got on the go pedal and it had a pretty decent semi type sound to it. I am guessing it must be a rebadged f350 or something. I think the vanity plates said mtlman1 or something. Pretty cool looking ride being a Ford and all.

 

probably a 250/350 with 550 badges, ive seen a few here,and every time that was the case,you can see the huge dana 135 axle on the true 550,and the alxes have 10 lug nuts.

 

If it sounded like a semi, it wont no powerstroke. May have been a Cummins.

 

I saw one of those here in town also...same thing...I looked at it and thought, "No way..." I think somebody likes to feel big w/ that badging...maybe that's what makes him go so fast!
