Remember riding in the back of the bus going to school?? Yup, that's how they ride. Kinda stiff and you are right over the axle=maximum input to you for every bump.
The floorplan up front is very restricted do to the doghouse. Moving around is kinda hard due to climbing over center hump. Most conventionals are easy access due to the lack of protrusions from the floor area.
COE have been on the decline since most of the length laws have allowed bigger trucks. Most manufactures don't even over a COE anymore.
I do like the looks of a COE, but like the old days of calling them "Widowmakers", you are the first to the scene of an accident
. The new Argosys and such are aerodynamic, but ugly compared to the old school flat noses. Guess I'm biased
