Hi
We have had two motorhomes based on the 2.8jtd Fiat and both of them ran at about 55 mph when at 2000 revs. We have just got a used van based on the same engine and find that at 2000 revs it is running at about 47 mph. This van is 1 metre longer than our others - could this be the difference or could it be a sign of something else? As we do about 9000 miles a year will this make a great difference to our fuel usage? Any info greatly appreciated.
