Travco VIN location on 1971 270?

[Dodgy71]

Does anyone know where the Travco VIN is located on a 1971 270?\nI have the Dodge chassis VIN (on left side of radiator behind the radiator access door), but my original California registration say the VIN is "B" then 5 numbers then "E". I can not find this number anywhere on the MH. There is a laminated type paper sticker on the interior wall just behind the drivers side window, that has "VIN:" but nothing after that. I'm not sure if the lettering faded away, or if it was never typed in.\n Anyhow, trying to re-register and if the VIN on the old registration can not be found, I'll just try to use the chassis VIN, which is what most refer to anyway.
