The first one I am going to put together is my own vehicle, a 2nd generation Dodge Durango (2004-2009).
I started with the base VIN of mine, compared to other Chrysler decoders and extrapolated more as I went along.

Dodge Durango VIN Decoding:
Digit:
1st Country of Origin
- 1 - USA
- 2 - Canada
- 3 - Mexico
- 4 - US Diamond star motors (typically motor homes)
- J - Japan (shouldn't see this)
- D - Dodge
- C - Chrysler
3rd Vehicle type
- 4 - Passenger (private) vehicle
- Other digits may show here if it was a fleet, corporate or non-standard Durango
4th Gross Vehicle Weight Rating
- H - signifies GVWR of 6,001 to 7,000 lbs. which all Durangos should fall under.
- Only a V6 ST model may have "G" which is 5,001 to 6,000 lbs.
- Another possibility is that this was used for axle ratios and not GVWR, in which case H = 3.92
- D - 4 door
- there may be other letters here, please let me know if yours is different and the extra info to go along with it such as 2 or 3 rows of seats, ST, SLT, Limited, etc... there may be more that is not shared here.
- 3 - ST
- 4 - SLT
- 5 - Limited
- This may also signify the engine and not the series or have more options such as "4.7L ST", "4.7L SLT", I am waiting for more information before finalizing this section.
- 8 - 4x2?
- N - 4.7L V8, 289 cid
- M - 3.7L V6
- P - 5.7L Hemi V8 318 cid

Every now and then a VIN does not follow the normal convention mentioned above, such as the 8th digit has been found to contain the digit for the V6 yet the vehicle has the 4.7L V8. As vehicles are rolled off the line, if the V6 was not up to specs, they may have made a last minute decision to replace it with the 4.7L. Another possibility is the V6 engine blew with low miles and the dealership or mechanic shop replaced it with the 4.7L at that time.
Position 9 is from a Check Digit calculation:
The United States of America and Canada require that the 9th position of the
Vehicle Identification Number is to be used as a check digit to provide a means
for verifying the accuracy of the VIN transcription. It is calculated by using
the other 16 characters of the VIN to generate a single digit number.
- A numerical value is assigned to letters in the VIN. I, O and Q are not
allowed so their positions are skipped. A=1, B=2, C=3, D=4, E=5, F=6, G=7,
H=8, J=1, K=2, L=3, M=4, N=5, P=7, R=9, S=2, T=3, U=4, V=5, W=6, X=7, Y=8,
Z=9 - A weight factor is assigned to all positions of the VIN, except of course
to the 9th position (the check digit itself), as follows: 1=8, 2=7, 3=6, 4=5,
5=4, 6=3, 7=2, 8=10, 10=9, 11=8, 12=7, 13=6, 14=5, 15=4, 16=3, 17=2 - The numerical values of the letters in the VIN are multiplied by their assigned
weight factor. - The resulting products from step 3 are added up.
- The sum of the products is divided by 11.
- The numerical remainder (0 through 9) is the check digit.
- If the remainder is 10, the check digit is the letter X.
- So the 9th position of the VIN will be a number 0-9 or the letter X.
