Yes, no way was this made in 1965. Al Lewis is clearly much older than he was when he was making The Munsters in the mid-60s. He did have a renaissance with this character in the mid-to-late '80s, so I suspect that's when it was really produced.
As far as his name goes, on The Munsters he was known as "Grandpa"; so I think changing it to "Grampa" got them around the copyright law. (Funny, though that his pet bat on the TV show was also named Igor; I suspect that you can't copyright a real name.) It's hard to say which is worse--the inane dialogue he's spouting or the trailers from the actual movies. But a job is a job, and you can tell that Al Lewis is a veteran pro, and he does a splendid job with what he has to work with. The movie trailers are ridiculous, which makes them enjoyable in their own way: we get to see how many different methods monsters of various persuasions used to destroy the earth a few decades ago.
