Why do people choose cargo vans over motorhomes?

I understand the appeal of the being stealthy but many van conversions look quite obvious like campervans. Even if people try to keep the exterior simple, features like solar panels on the roof often compromise the stealth factor.

Another reason I’ve heard is that motorhomes are big and heavy. However, some motorhomes are the same size or even smaller than popular cargo vans like the Ducato L4H3. Additionally, it’s often easier and much cheaper to find a low-mileage motorhome

I know motorhomes can have issues like rotting wood, but if you're buying a cargo van to convert, you likely already have the tools and skills to renovate the interior. And if you’re looking to buy a pre-converted cargo van, you probably have the budget to afford a new motorhome instead

In my opinion, RVs are more suitable for living, so why choose a van instead?
