If your lady loves you and still wants to enjoy RV'ing with you.....she would learn how to drive the MH. With a competent teacher she could learn how to drive it.
I taught a elderly lady that her husband had just died and she had never driven the MH.
Her kids where 'very' quick to put the MH and toad up for sale. That is how I came upon her situation when I answered the ad.
Talking with her I found out she really liked Rv'ing. They were full timers.
Albiet the sale price on that MH/toad was one sweet deal I passed on it and instead I went over to her house every night to give her lessons and over time I taught her how to drive it and learn all the functions.
I'm proud to say she is back on the road solo and has joined several solo RV'ing clubs.
It still puts a smile on my face when she sends me postcards. :C
Don't give up. Find someone that will show her how to drive the MH. So the both of you can enjoy the life of RV'ing together.
BTW: Look up Good Sam club and Escappes Club and read their local club memberships. They both have clubs especially organized to help people with health issues. You shouldn't have to join to look at the list.
Good luck I sincerely hope your significant other considers learning how to drive the RV.
We must be willing to get rid of the life we've planned,
so as to have the life that is waiting for us.
