I am going out on a limb here but if I were reading between the lines my guess would be your wife is not just a homebody but probably has strong family values and she might feel that leaving the home front in a motorhome a little more permanent for a lack of better words, she is ok with those weekends away from home but to set off for multiple weeks/ months as a lot of rv'ers do could be the catch.
Pick out some great things to do in an RV
Wife and I took our first big retirement trip in Oct to Albuquerque Balloon Fiesta 500 hot air balloons going up in a two hour period.

Anyway good luck with your search as to whether motorhome is in your retirement journey.
I see you just joined yesterday welcome.
