Thanks for the quick replies. I should have stated it is a 2012 Salem Cruise 221RBXL.
I have VIN, tire, etc. info on the inside of the door frame, but no serial number. Why would there be no serial number on your title or documentation?
I'll check for a serial number on the tongue. I'll go take a picture.
I went out and took a picture. I have posted pics before. Now I'm having a brain fart on how to upload.
Okay, here it is. Is this the serial number? I guess I should reinstate that the form in OP was asked for a Unit Serial Number but had forgot to mention that it asked for a Unit VIN as well. Hope it clears that up.
