DW started to show signs of the disease about 5 years ago. Nothing serious. Forgot to turn water taps off; forgot to turn stove off; made lunch and then went to make another.
We decided at that time that she would not drive anymore. We were concerned that she could mistake the brake for the gas pedal or the other way around. I did all driving from that time on.
As the disease progressed, she demonstrated fits of extreme anger, sometimes violence, and extreme strength. She is normally a very quiet person. She often left the house to "go home" and we had to go find her at any time of the day or night and in all types of weather.
She is now in the late middle stages of the disease and has calmed down somewhat. Still a challenge every day to survive a little longer. She requires about 95 % care at this time.
I am no expert of the disease. I have to struggle every day to try to understand what she is going through. I only provide you with the above details so you know that I have experienced what you will go through.
My advice to you is that you should not continue to drive. If your spouse can handle the RV and all the work that goes into it, and if your spouse is a very calm person and can handle the angry outbursts, while driving, then you could continue for about two years.
Think carefully about the effect the disease will have on your spouse and whether she can handle it or not. That is the main issue that you have to answer.
I wish you the best of luck.
