Greetings all, I’m writing a book about 1970’s Shasta trailers, and a large part of it will be identifying trailers. Ads and sales brochures have excellent photos to help identify models for each year. I’ve collected full line dealer catalogs for 1973, 1976-1979 but I can’t seem to track down anything for 1970-72, and 1974-75. Anybody out there have magazine ads, brochures, etc. for these years they would be either willing to scan and share or sell? Thanks in advance!
