What year would you look for?

Shop around and see if you can find a Diesel class C. I had the V-10 and it was so sick on HP and torque it would change gears going up and overpass. We were very displeased with the V-10 version. Shopped around and found a 2009 Coachmen Concord with the 6.4 diesel and there is a thousand times difference in the performance and the fuel mileage is 1/3rd better. Not to mention the life of the engine. Can't imagine why they even put gas engines in a vehicle that large.

The E450 doesn't have room in the engine bay for the 3 valve version.

Hello all, we are beginning our search for a used Class C and have 3 questions.

1). In what year did Ford switch from the 4 speed automatic to the 5 speed Torqshift transmission?

2). What years of Ford engines had insufficient spark plug threads?

3). I have heard that Ford Class C motorhomes use only engines with 2 valve cylinder heads instead of the commonly found in Class A's, is this true?

Thanks in advance.

For what it's worth, I copied each of your first two questions and did a google search, and cam up with answers of 2003, for question # 1 and 1997-2003 for question #2. :B
Those are cab and chassis model years, which could very well be different from the RV model year on those vehicles.
It is true that Class Cs have the 2 valve V10, while Class As have the 3 valve. I believe the difference is 305HP for the 2 valve, compared to 362HP for the 3 valve version.
