Small business with camping bus rental

The last thing I thought about looking at Youtube videos about camping bus Individual expansions, you could start a rental of such extended camping buses. Due to the current situation camping is always more in demand than ever and therefore the demand for cheap camping buses should exist even with younger people. I would consciously do without too much luxury in the vehicles and keep the equipment consciously quite spartan. So for me neither television nor Internet for camping holidays in nature. I would also use used base vehicles to keep the financial use as low as possible. However, I have no idea what the equipment costs then. Then of course there are also official requirements. I find these self-developed camping buses somewhat iconic. However, since I am working and by the way pay off a condominium, I can not make a year on Wild-Vanlife. Such a camping bus and then because of the main job can not use it so often, is also stupid. Stand around, costs tax and insurance so I can rent this thing if I don’t need it myself. Is that possible, or is it not financially worth it?
