Quality of life is always in the forefront of my decisions. I try to indulge my husband’s desires while at the same time weigh safety & finances. My suggestion is that you rent an RV for a week or two & see how that goes. They aren’t cheap but it’s way less of an investment than buying one. There’s no way of knowing up front if it will be a positive experience. Dementias are strange beasts. One can still have dreams & goals but the reality of them could be a nightmare. I learned my lesson when I booked a 7-day trip to Florida (one of my husband’s bucket list items). Once airfare, hotel, and vehicle rental were confirmed & paid for he started obsessing on strangely minor details - such as getting from the airport to the hotel (just a couple of blocks). His anxiety continued to grow over the next few days. I ended up having to cancel the trip & forfeit $2,500+ in expenses. (I hadn’t felt the need for trip insurance.) Now I plan virtual trips & provide my husband with all the details of the plane, lodgings, maps of the area, etc. When his anxiety kicks in I “cancel” the trip. In the event the anxiety didn’t kick in (and it always does) I’d tell him trip was canceled due to XXX. I could use possibility of delayed flights, or concern about covid, etc. This way he still gets to dream & plan.
