How does a truck camper fit into a truck bed?

Sorry for the ignorance. How does a truck camper 'work?' Say a TC's length is 6.5' and a truck bed is 5.5'. Obviously, the tailgate cannot be up. Do you remove the tailgate or just lay it down? If you do remove it, why? Will a 6.5' TC fit into a 5.5' bed?

Secondly, how do you 'tie down' a TC? Whatever it takes, does that come with the TC or do you have to buy something?

Is there any electrical wiring that needs to be hooked up to the truck? They don't have brake lights on them, just reflectors, right?

Thanks!
