If your spouse is ready to take on responsibility and follow you making sure everything gets handled with the RV along with watching over you full time (and assuming your doctor doesn't take issue)...go for it.
A lot of it will be up to your spouse as she will have a lot of responsibility but it's not like it will be better in the future. As long as you aren't putting others at risk, go down kicking and screaming having the best time you can as long as your spouse is willing.
As others have said, have an exit strategy if it becomes too much.
