I can’t figure out what my gear ratio is. I’d like to know how much my truck will/won’t haul. Rather than the normal door jam/glove box sticker showing the RPO codes or Service Parts ID code, my truck has a QR code. A QR reader app gave me the following codes:
AG1
AXK
AY0
AZ3
CJ2
C5Z
DL8
EF7
E63
FHO
G1K
H0U
IO6
I18
JD9
L83
MAH
MSL
MYC
NP5
NTB
QT0
RC4
RD4
RUF
UDD
UQ3
U2K
V8D
WMJ
X88
Z60
1LT
4AA
6YB
7YB
8X2
9X2
Please help. Thanks.
