Granted the 625 HP Catapillar C15 engine is awesome, but if you want to see something really neat watch a Z625 with steering tag axle turn around in 74 feet! That is amazing. A 45' motorhome can be heading north and in 74 feet turn in the opposite direction and head south. I saw one of these beauties make a 90 degree turn into one of the service bays. The coach just pulled right inside the building; it didn't have to pull up, then back up, then drive inside. It just turned in and drove inside - UNBELIEVEABLE! The tag axle actually steers 23 degrees in the opposite direction that the front wheels are turned. The result makes you do a double take. I took a picture at the Newell factory of a Z625 turning around; you can see the tag axle turning. If anyone would like to see it, just email me at
tugagaidry@bellsouth.net and I'll send it to you. :!:
