I disagree with Don's assessment of the ride. The Freightliner has four big air ride bags just like the Country coach would have. I have the Neway Freightliner and it is very smooth ride.
But if there is any doubt and maybe he did have too much air in the tires or something else wrong, take it out for a twenty miles test drive. That way you find out for yourself how it handles and how the ride is.
One thing I will say about the Cat 3126 B is that it has a deep pan and holds more oil then the shallow pan that is on the 3126-E holding exactly 19 quarts of oil. You add any more oil and it will just throw it out through the breather tube. Not the case if you just add the 19 quarts. Cat engine is bullet proof.
