What was the last year for Life Time Premier production

My baby (Rolling Home) Is a 1973 Life Time Imperial. Now I know that Winnebago made the Life Times for a while. A lot of the time when I see pics of some Winne interiors I find myself saying "That looks just like..."  about the appliances and such. Also the layout of the interior looks the same a lot of the time. Even, for instance I have noticed the hardware for the dinette table that lowers to make a bed is the same. All that being said, I was wondering if anybody knows what year Winne stopped making the Life Time  and if possibly this manual would be of help to a long lost  Winnebago cousin ? LOL

The last documentation I've seen and actually had in-hand was for 1974.
