Before you give up on the Bully look at the Bully Manual for the types of body structure they fit on. The Mercedes was not listed when I did my research but the body structure on one of the 4 examples was like my rig so I took a chance after you tube searches on installation.
Check out this link:

to see if your body structure is there.
If the link doesn't work do a search for the installation manual.
Good luck...
