"Different strokes for different folks". That's why there are so many different varieties of RVs out there for sale. As for us, my wife and I have been RVing for 34 year and have always owned motorhomes and towed a car.
As has been suggested, we initially rented motorhomes (3) before we decided to buy. Always good advice. Also when the RV shows start happening again, go and check out different rigs for size and livability. Again, some folks are happy with 25' of space and others need 40'. Only you can decide what would work best for you.
