I went to visit the XD (and it's new owners) today.  Took this photo and manipulated it to show a size comparison.  I can't remember exactly what the XD has, but I know it is either the 2" or 3" OME (Brent would know) and it has 235's on.  The '04 is stock.  It is one photo, but I cut and pasted the '04 to sandwich it into the XD, then scaled it so that the spare wheels were almost exactly the same diameter in the photo.  I also measured the roof lines from edge to edge and got them very, very close.  Then I lined up the two closest tires (rear right for XD, rear left for '04) so that they were as even as I could get them  So, without folding the mirrors together and parking them very close together, and measuring the camera angle, this is about as exact as it's going to get.

Enjoy, for what it's worth, maybe this will help someone when looking to do mods or something.
