Renting out your campervan in Europe

Im looking for information about peoples experiences who have rented out their campers in Europe whilst they haven’t been using them…
I am about to build my first camper :sweat_smile:
Which is both very exciting and a little daunting.
I will be living in it for approximately a year and intend on keeping it after I go home so I can return in the future and have a home to travel in.
What platforms have people found to be the best for using?
Has it been easy to rent out?
Any info would be greatly appreciated!
