There's an extra 'http' in the link above, this one goes directly there:

That's Chalet #0714, built in 8/76. I saw it in person several years ago, the owner wasn't at home at the time. If I remember correctly, the body wasn't plagued with the usual Chevy truck rust. The model year of the paint for the truck looks like '77, but it has '76 colored stainless steel trim on it. If I could get a hold of the owner and get the VIN, that might determine if it is a '76 or '77.
