I would be happy to help you, but your vin# is missing the prefix letter....?24191 and as Theresa mentioned, do you know what model you have? If not, can you measure the body (front to back) and the overall length (tongue to bumper)? These measurements will help with determining what you may have.
Based on the info on the DOH tag, your Shasta's vin# reads: ?S24191-??3928
Usually, the ?'s would have letters. In North Ridge, California, the first prefix letters were either D, DS, ES, FS, GS, HS or HT. The second set of ??'s would have been either FA or PA.
Now, all this being said, I believe your Shasta's vin# to read: GS24191 . If a title is or were available, this is how it would or have probably read. In 1965, based on the vin#s that I have collected from North Ridge, the last set of letters & numbers were really being hard to locate.
Would love to see some pictures of your Shasta and maybe we can help determine the model that you have.
