We used to rent for several years before buying and rented a variety of Class C's from 24 to 32 feet.
Pros
Get RV experience without a huge investment. 1 week total cost comparable to renting a decent vacation home + driving your car somewhere. But mobile instead
Get to try out various models
No need to store or maintain RV or think about when not using
Not insuring RV when not being used
Always got to take the dog
Worked well when we wanted to RV 1 or 2 times/year. Later when we wanted to go more we bought
Cons
Auto insurance policy no longer covered RV, had to buy daily insurance from RV rental place
How well maintained are the RVs? Other renters make a lot of mistakes and are careless so there may be hidden damage. We had rigs where the brake light came on when pressed, toilet leaked on floor (previous renter drove over something and tore off black tank, not correctly repaired).
With our own rig we know exactly how it is maintained.
Have to schedule in advance for peak season
Have to eat cleaning charges since no desire to clean when getting back from trip. Usually did a quick clean on interior but exterior cleaned only 1-2 times.
Need a 10 day rental to allow for pickup and return days, loading and unloading, to yield 7-8 days of travel
loading/unloading quickly is a chore
How are water hose (bought own) and sewer hose?
Don't know exactly which motorhome or what condition you will get when rental time arrives, rental place may substitute another unit...got a 32 foot one time when we wanted a 26 foot.
