For anyone who’s interested, (from this thread, second page) my dad’s surgery went very well. He was able to be released from hospital 5 days after he checked in (which was about what they thought).
He is recovering nicely, and his prognosis is excellent - he is expected to make a full recovery. Of course, now he has a big honkin’ motor home on his hands, and no Last Trip of a Lifetime to take with it, but that’s ok really. 
Mr. Wonderland and I managed to get down to North Dakota (Grand Forks) for a couple of days and had a very nice time - we went shopping and antique-ing, and we rummaged around Cabalas for about 3 hours so it was a bit vacation-y.
Thank you to everyone who sent me PMs, and for all the well wishes for my dad.
