Is there a decoder for Winnebagos to identify what year they were manufactured?
There should be a manufacturer's sticker somewhere in the RV that will indicate the build date. Also, you can put the VIN in one of the online VIN decoders and it will tell what year the chassis was built.
I know its a 217 1/2 T and I have the serial and mfg. #. Still trying to find the vin#. I think its's somewhere on the tongue.
I think it may be a 1966.
Sorry, Joe. I was thinking of a motorized RV with my "VIN" response. Since you have the serial # and model, you might try calling Winnebago and see if they can shed some light.
