Truck camper, van conversion or rv?

[RMHenna]

Wanting to buy but have questions. What are pros and cons of each? On the surface, a truck camper seems very versatile, though I rarely see people who own them take them off. That defeats the versatility. are they easy to take on and off? Conversion vans can be good, they're smaller, but seems to be a pain in the back pockets going from travel/meals, to sleep. Next are the smaller RV which seem to be a great overall option but don't know what challenges exist.
Any objective considerations appreciated.
