Haha reading this after a few beers, none of my trucks are sleek unless you count the C120 freightliner with a fuel guzzling C16. I have a soft spot for that truck, service her and spin it back to work. near on 20 0000hrs on the engine, cost to keep it on the road are very low. The Cats do a good job for me on triples over here with no real difference in fuel burn. The only thing that is better on fuel is the new 909 (brick pushing through the air) with an X15. It averages 1.1 - 1.2 klm/litre. Had an 871 damn near sent me broke until I learned to fix it. Don't own it anymore. As far as I can see a Cat will burn slightly more fuel towing a single trailer but this is outweighed by lower maintenance costs. Anyway the biggest influence on fuel burn is the steering wheel attentant.
