vin

I am currently looking at a Hi lo camper and the individual selling it only has a bill of sale. He has stated that it is a 1971. But the model # 17572R makes me think it is a 1972. Any help would be appreciated.

Hi, y'all I'm new and just bought a remodeled 1999 Rockwood Premier pop up. Can anyone please tell me where I might find the VIN? I've crawled all underneath and searched the tongue also. No luck. I don't have title and the girl I bought it from doesn't remember the original owner's name...

Other than sticker driver side near front and sticker in wardrobe closet, where is the VIN visible on trailer? 73/gus
