Tnx for that updated 350 info Phil.
P.S. It seems like it's more difficult nowadays to locate all of the E-series detailed specs that were available some years ago when we bought our E450 based Class C. The specs I used to have access to showed E350/E450 differences in such areas as - frame thickness, driveshaft diameter, power brake booster type, spring stiffness, front/rear torsion bars (rear only on E350, both front/rear on E450), differential ring gear diameter, drive axle spline count, etc..
:) U got that right ! They don't want us to know too much info.
