It's a 2006 Gulfstream Indepence, F53 Ford chassis. Removed the S110 axle 19.5's and put the big Spicer S150 axle in myself along with front hubs to change over to the 22.5 wheels/tires. Big job. Like everything, Ford doesn't make anything easy, even the part numbers and diagrams are impossible to find.

You guys need to post up photos of your RVs. That picture in your profile Ray just isn't enough to go on.
