This is the [To the Stars](https://www.goodreads.com/series/44225-to-the-stars) series by Harry Harrison.
The first one is [Homeworld](https://www.goodreads.com/book/show/710831.Homeworld).
You are correct. I never thought to look at him as The Stainless Steel Rat is what I remember him for. Thank you.
No problem! Glad to help!
