Dumb question about truck camper tie downs

OK, so looking at all types of truck camper pictures, both on and off trucks I have noticed that most all truck campers are "tied" down to truck with the same type frame mounted system from various manufacturers, but basically the same concept.

I am referring to the type like the Torklift systems.

Every picture I see of a camper on a truck with this system, the mounting parts, happyjack, turn buckles etc. are all vertical. Straight up/down from the mounting point on the truck and camper.

So what keeps the camper from sliding out the back of the truck on steep inclines or any other situation where the truck would be pitched to where something would slide out the back.

With the "ties" vertical, there would be, what about 2 foot of room for them to slide backwards (away from the cab). The front of the bed keeps it from moving forward(toward the cab) but what keeps it from moving out the back?

Again, just looking at pictures it looks to me if you pulled off a little hard on a incline, the thing would slide back a few feet. So tell me why it wont.

Most, if not all, truck camper manufacturers recommend that a rubber bed mat be installed between the truck bed and the camper bottom. This mat keeps the camper from sliding front to back and side to side. Pickups do not have enough power/traction to climb a hill so steep that the rubber mat would allow the camper to slide rearward. The front bulk head of the truck bed keeps the camper from sliding forward during a very harsh sudden stop.
