Firstly, I’m just another “Joe Shmoe” like you. This is the first time I have used this approach for HD trucks from Mexico. I have been doing something similar for the TRX’s coming out of SHAP for members of the RAMTRX forums. I assume the same build sheet scanning approach I am using for SHAP VINs would apply here as well so I adjusted for the differences in VINs for all the HD trucks and scanned your list. It also returned VINS that matched all the full VINs already in the list from just the sequence so I would personally feel confident in using them.
Also, four new window stickers tonight.
NG100534
NG104736
NG117337
NG117404
Thanks for the heads up about those window stickers. For some reason, the window sticker and equipment listing URLs don't always return the listing for me. I have to sometimes try multiple browsers/IPs (VPNs). Do you mind sharing info with me about how you're checking the URLs? Presumably programatically rather than manually.
So, without the ability to check that a VIN exists in a Stellantis system, here's my concern:
Given a sequence number like NG121685 which we know is a
3500
Big Horn
Mega Cab
6.7L Cummins
What I don't know is if it is SRW (R3L) or DRW (RRL). Both of which would be easy to construct a valid VIN for given we know how to calculate the check digit.
And that's a relatively straighforward example because the mega cab only comes in 4WD and a short bed. For other sequence numbers, where those configurations come into question, there are even more potential VINs.
So, I've taken a more cautious approach to only list VINs I am nearly confident are correct. As I don't want to mistakenly assume a VIN is correct and continue to not find the equipment listing and window sticker and assume there's more of a backlog to be built than there really is.
I had thought about constructing all the possible VINs for orders I don't have complete info for and then constantly checking all of those potential VINs. But I haven't had time. One night I even had a more crazy idea to construct all possible VINs for every possible sequence number. But I regained my sanity shortly after.
Tell me if I'm being silly and am over thinking this. I do find this a fun problem.
