I'm not exactly sure where to find the frame VIN, but stamped on the frame under each door are the below numbers:

Under Driver Side Door: 3998723 262 5 26 34

Under Passenger Side Door: 3998724 262 6 9 34

Not sure why these numbers don't match, but I'm new to all of this.

Thanks for everyone's help in trying to figure out exactly what this is. I think you are probably correct on the wheel base. I haven't pulled a tape, but am betting it is the 127" LWB.
