EGR

[cleaving@domain.elided]

Hey IH'ers!

 There's something that's been bugging me that I don't understand. Both my
Scout and my Travelall are '75s, but the Scout has an EGR and the Travelall
doesn't. I know the Scout GVW was raised to 6200 lbs. in '75 to avoid some 
emissions equipment requirements (air pumps? catalytic converters?) - was 
there another weight cutoff that removed the need for an EGR? The Travelall 
GVW isn't that much more (6900), so that doesn't seem like the answer. Does
anybody know?
